Abstract

The procedure of first COMpresssing and then exPAND-ing a signal is known as "companding." In PCM systems, commonly used in telephone switching networks, samples of an analog speech waveform are encoded as binary words and transmitted. Large dynamic range speech is most efficiently encoded and transmitted if the amplitude of the waveform is compressed before transmission and then expanded at the receiver. This paper describes a homomorphic approach to companding. It reviews and illustrates how these signals are processed and used in speech processing and communication networks.
