Palghat P. Vaidyanathan (born in Kolkata, India on 16 October 1954) is a Professor of Electrical Engineering at the California Institute of Technology, Pasadena, California, USA, where he teaches and leads research in the area of signal processing, especially digital signal processing (DSP), and its applications. He has authored four books, and authored or coauthored close to five hundred papers in various IEEE journals and conferences. Prof. Vaidyanathan received his B.Tech and M. Tech degrees from the Institute of Radiophysics and Electronics, University of Kolkata, and a Ph.D degree in Electrical Engineering from University of California Santa Barbara in 1982.
Contents
Prof. Vaidyanathan's pioneering contributions include the development of the theory and structures for filter banks, especially perfect reconstruction and orthonornal filter banks, which find applications in data compression standards such as JPEG and MPEG, and in digital communications. One of his early contributions is the development of the theory of robust digital filter structures directly in discrete time without recourse to classical circuit theoretical models. He has also contributed widely in other areas of signal processing including image processing, genomic signal processing, sampling theory, optimal transceivers, radar signal processing, and sensor array processing. He has also explored the role of number theory in signal processing applications.
