Issue No.10 - October (1976 vol.9)
The great power, versatility, and availability of digital computers and processors has led to an explosive growth of interest in digital signal processing. Several very good books have been written on this subject (for example, see Oppenheim and Schafer<sup>1</sup>and Rabiner and Gold<sup>2</sup>). These presentations are basically classical signal processing adapted to digital processing techniques. As such, the only orthogonal functions considered are the Fouier transformations. However, a rather large body of literature has appeared in recent years suggesting that non-sinusoidal orthogonal transformations may be more useful in a number of digital signal processing applications. In this book, Ahmed and Rao fill a long-felt need to assemble and condense this material into a coherent presentation for the graduate engineering student as well as a body of introductory material for the practicing engineer.
