I have 36 years of experience and specialize in the field of electrical and computer engineering, with specific knowledge of data acquisition, switch-mode power supplies, and speech processing and recognition. I have published on such topics as data acquisition for nuclear physics experiments, improving the performance of analog to digital converters and use of field programmable arrays (FPGA) for sonar systems. I have testified on basic concepts of digital signal processing, speech recognition and graphics color palettes (RAM-DACs) for a patent infringement case.
