Book Description
In this annual report of electronics research at the University of Texas at Austin, we describe recent findings, progress, and future plans in the areas of solid state electronics, information systems, electronic computers, electronic controls, plasma and quantum electronics, and radio sciences. Among the many project reports in these areas are a number of significant findings. In the solid state area, a study of the transition layers between CVD VO2 films and oxide substrates reveals complex substrate-film interactions with significant implications for VO2 and other material-oxide substrate systems. The investigation of computer architechture for byte string and vector operations, in the information systems area, shows iterative processing of variable length operands to be feasible. In the area of electronic computers, errors have been reduced and reliability increased with minimal redundancy, through the use of functional simulation of logic nets. A fourth significant report appears in the electronic controls section. An easily implementable, suboptimal estimator has been developed and applied to problems in satellite orbital perturbations and in optical phase tracking. There were two developments of interest in the plasma and quantum electronics area. First, digital bispectral analysis has proved to be a useful tool for the interpretation of nonlinear wave interaction data. In particular, this technique permits one to discriminate between spontaneously excited and coupled modes, and to measure the strength of the interaction or coupling coefficient. A second significant article reports a general unifying theory for incoherent optical convolvers and correlators.
