Book Description
Narrow Band-pass filtering techniques have been a challenging task since the inception of audio and telecommunication applications. The challenge involves keeping quality factor, gain and mid-frequency of the filter independent of each other. The critical applications require a design that ensures mid-frequency immune to the circuit component tolerances. It becomes increasingly difficult for low-frequency applications where the shift in few Hz in mid-frequency would cause desired frequencies to fall outside the filter’s bandwidth and go undetected. The selection of right topology of the filter for the best performance is the key to successful design. This book objectively compares the relative performance of none popular narrow band-pass filter topologies. The filter topologies are evaluated using a real-world practical example of designing an extremely narrow band-pass filter. The book provides guidelines for selecting the right topology for the low-frequency narrow band-pass filter.

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
With the continuous development of social economy and the improvement of computer science, communication engineering and electronic engineering, automo-biles are also gradually transforming from mechanical products driven by internal combustion engines to intelligent products driven by electricity. The electrification and intelligence of automobiles have brought new problems to society: on the one hand, electrically driven vehicles have lower operating noise, which makes pedestri-ans’ perception of vehicles weakened; on the other hand, with the deepening of intel-ligence, the control of vehicles will gradually be yielded from drivers to vehicles, which will largely cause the lack of human-vehicle trust. If these two problems are not solved, they will largely affect the efficiency of future road traffic and even bring potential danger. Therefore, it is necessary to explore a vehicle external sound effect as the external interaction interface of future vehicles to improve human-vehicle per-ception and enhance human-vehicle mutual trust. This paper takes the external sound design of quiet vehicles as the starting point, and divides the external sound design of vehicles into two aspects: quality design and functional design through literature research and combing of sound design related theories and methods. In the research of quality sense design, the paper explores the sound quality categories suitable for quiet vehicles based on human perception of sound quality, and realizes the decomposition of quality sense design elements through psychoacoustic experiments, and constructs the relevant design models, which provides theoretical guidance for the design of quality sense of exterior sound effects of quiet vehicles. In the functional design research, this paper conducted an in-depth investigation and study of human-vehicle conflict based on China’s road en-vironment and traffic participants, extracted a total of four categories and six types of human-vehicle interaction needs, and accordingly designed, optimized and verified the interaction information, and explored the design strategy of functional sound ef-fects.
