P. P. Vaidyanathan. Palghat P. Vaidyanathan (born in Kolkata, India on 16 October 1954) is the Kiyo and Eiko Tomiyasu 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 six 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, Science College campus of University of Kolkata, and a Ph.D. degree in Electrical Engineering from University of California Santa Barbara in 1982.

Prof. Vaidyanathan's pioneering contributions include the development of the theory and structures for filter banks, especially perfect reconstruction and orthonormal 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.
