Pulse Code Modulation and Its Variants
Wai C. Chu · 2003
This chapter can be considered as an extension to Chapter 5, where scalar quantization is discussed in detail with the material applied to any signal type. In this chapter, however, the focus is on speech samples. The chapter is organized as follows: performance of uniform quantizers is first found, followed by standardized nonuniform quantizers; the idea of differential PCM is given, and several adaptive methods are spelled out at the end.
