Book Description
We are living in a time when many people are feeling the weight of the world on their shoulders, in the form of global and personal stress--financial challenges, illness, loneliness, depression, and lack of purpose. "Zero Frequency", by Mabel Katz, is an illuminating book that offers all struggling citizens of this planet a path out of turmoil and towards a life of happiness, peace, and abundance. As a lifelong practitioner and leading authority on Ho'oponopono, the ancient Hawaiian art of problem-solving, Mabel Katz's new book presents wisdom in a more practical and modern way--one that simultaneously speaks to the mind and heart, while also cutting through many of the mind traps and illusions that prevent us from experiencing truth. In this book, you will come to understand that "Zero Frequency" is a direct pipeline back to who we are--to our true essence. "Zero Frequency" is also a suspension of mind and thought that would allow us to return to the fullness of the Present Moment. Mabel calls this a return to our natural state of Zero--the limitless state that comes when we live in the Now--present, conscious, free of judgment--allowing our hearts to open to the wisdom that already lives within each of us. This book will lay down a concrete path to help its readers wake up and realize their potential. It is a book that is written with the unwavering belief that the more we help (and heal) ourselves, the more we help (and heal) the planet. Living from who we are is at the core of "Zero Frequency", a combination of gratitude, letting go, and practicing peace. "Zero Frequency" is like returning to our childhood, and the joy and innocence we have lost as time and age have buried who we are. Rediscovering this part of ourselves--our true self--is the pathway back to opening our hearts to abundance, peace, and joy. It is where all the answers to life's problems will be found. It is the heart and soul of "Zero Frequency".--Publisher.

Book Description
"The DFT can be understood as a numerical approximation to the Fourier transform. However, the DFT has its own exact Fourier theory, and that is the focus of this book. The DFT is normally encountered as the Fast Fourier Transform (FFT)--a high-speed algorithm for computing the DFT. The FFT is used extensively in a wide range of digital signal processing applications, including spectrum analysis, high-speed convolution (linear filtering), filter banks, signal detection and estimation, system identification, audio compression (such as MPEG-II AAC), spectral modeling sound synthesis, and many others. In this book, certain topics in digital audio signal processing are introduced as example applications of the DFT"--Back cover

Book Description
This book addresses the theoretical and practical circuit and system concepts that underpin the design of reliable and reproducible, high performance, monolithic feedback circuits. It is intended for practicing electronics engineers and students who wish to acquire an insightful understanding of the ways in which open loop topologies, closed loop architectures, and fundamental circuit theoretic issues combine to determine the limits of performance of analog networks. Since many of the problems that underpin high speed digital circuit design are a subset of the analysis and design dilemmas confronted by wideband analog circuit designers, the book is also germane to high performance digital circuit design.

Book Description
This textbook is an introduction to microwave engineering. The scope of this book extends from topics for a first course in electrical engineering, in which impedances are analyzed using complex numbers, through the introduction of transmission lines that are analyzed using the Smith Chart, and on to graduate level subjects, such as equivalent circuits for obstacles in hollow waveguides, analyzed using Green’s Functions. This book is a virtual encyclopedia of circuit design methods. Despite the complexity, topics are presented in a conversational manner for ease of comprehension. The book is not only an excellent text at the undergraduate and graduate levels, but is as well a detailed reference for the practicing engineer. Consider how well informed an engineer will be who has become familiar with these topics as treated in High Frequency Techniques: (in order of presentation) Brief history of wireless (radio) and the Morse code U.S. Radio Frequency Allocations Introduction to vectors AC analysis and why complex numbers and impedance are used Circuit and antenna reciprocity Decibel measure Maximum power transfer Skin effect Computer simulation and optimization of networks LC matching of one impedance to another Coupled Resonators Uniform transmission lines for propagation VSWR, return Loss and mismatch error The Telegrapher Equations (derived) Phase and Group Velocities The Impedance Transformation Equation for lines (derived) Fano's and Bode's matching limits The Smith Chart (derived) Slotted Line impedance measurement Constant Q circles on the Smith Chart Approximating a transmission line with lumped L's and C's ABCD, Z, Y and Scattering matrix analysis methods for circuits Statistical Design and Yield Analysis of products Electromagnetic Fields Gauss's Law Vector Dot Product, Divergence and Curl Static Potential and Gradient Ampere's Law and Vector Curl Maxwell's Equations and their visualization The Laplacian Rectangular, cylindrical and spherical coordinates Skin Effect The Wave Equation The Helmholtz Equations Plane Propagating Waves Rayleigh Fading Circular (elliptic) Polarization Poynting's Theorem EM fields on Transmission Lines Calculating the impedance of coaxial lines Calculating and visualizing the fields in waveguides Propagation constants and waveguide modes The Taylor Series Expansion Fourier Series and Green's Functions Higher order modes and how to suppress them Vector Potential and Retarded Potentials Wire and aperture antennas Radio propagation and path loss Electromagnetic computer simulation of structures Directional couplers The Rat Race Hybrid Even and Odd Mode Analysis applied to the backward wave coupler Network analyzer impedance and transmission measurements Two-port Scattering Parameters (s matrix) The Hybrid Ring coupler The Wilkinson power divider Filter design: Butterworth, Maximally flat & Tchebyscheff responses Filter Q Diplexer, Bandpass and Elliptic filters Richard's Transformation & Kuroda’s Identities Mumford's transmission line stub filters Transistor Amplifier Design: gain, biasing, stability, and conjugate matching Noise in systems, noise figure of an amplifier cascade Amplifier non-linearity, and spurious free dynamic range Statistical Design and Yield Analysis

Book Description
A digital filter can be pictured as a "black box" that accepts a sequence of numbers and emits a new sequence of numbers. In digital audio signal processing applications, such number sequences usually represent sounds. For example, digital filters are used to implement graphic equalizers and other digital audio effects. This book is a gentle introduction to digital filters, including mathematical theory, illustrative examples, some audio applications, and useful software starting points. The theory treatment begins at the high-school level, and covers fundamental concepts in linear systems theory and digital filter analysis. Various "small" digital filters are analyzed as examples, particularly those commonly used in audio applications. Matlab programming examples are emphasized for illustrating the use and development of digital filters in practice.

Book Description
Principles of Biological Regulation: An Introduction to Feedback Systems presents some understanding of control, regulatory, and feedback mechanisms in biological systems. This book discusses concepts related to the dynamic behavior of both individual biological processes and systems of processes that make up an organism. Comprised of 10 chapters, the book also describes the characteristics of biological feedback systems, focusing on the physical concepts. After briefly dealing with involved regulatory processes in biological systems, the book goes on discussing the flow or transport of material through a series of processes in the steady-state. Next chapter uses superposition principle to explain the changes that biological systems undergo following a disturbance or under dynamic behavior. The subsequent chapters cover the fundamental principles of negative biological feedback and to the effects it produces both under steady-state and dynamic behavior. Other chapters describe the effect of sinusoid signals on biological processes and present some stability criteria applied to technological systems and also their value in the study of homeostatic processes. The book also discusses some aspects of homeostats that seem to distinguish them from technological feedback systems. These features include not only the components themselves and their organization, but also the experimental problems involved in their study. The concluding chapters describe nonlinear behavior with great relevance to homeostatic systems and rate processes (production or destruction) for which the roles of stimulus and initial conditions are different. Mathematical relations developed from the conservation of mass and the mass action for chemical reactions are also presented. The book is an invaluable resource for life scientists and researchers.

Book Description
This textbook provides an introduction to the study of digital signal processing, employing a top-to-bottom structure to motivate the reader, a graphical approach to the solution of the signal processing mathematics, and extensive use of MATLAB. In contrast to the conventional teaching approach, the book offers a top-down approach which first introduces students to digital filter design, provoking questions about the mathematical tools required. The following chapters provide answers to these questions, introducing signals in the discrete domain, Fourier analysis, filters in the time domain and the Z-transform. The author introduces the mathematics in a conceptual manner with figures to illustrate the physical meaning of the equations involved. Chapter six builds on these concepts and discusses advanced filter design, and chapter seven discusses matters of practical implementation. This book introduces the corresponding MATLAB functions and programs in every chapter with examples, and the final chapter introduces the actual real-time filter from MATLAB. Aimed primarily at undergraduate students in electrical and electronic engineering, this book enables the reader to implement a digital filter using MATLAB. Deliver the conceptual knowledge of digital signal processing with extensive use of the illustrations from practical viewpoint. Also, the digital signal processing is initiated from the digital not from the continuous domain.
