摘要：

Architecture and design of a monolithic voice CODEC is described. The CODEC consists of 2 chips-the transmit chip includes the companding coder (nonlinear A/D) along with filtering functions, and the receive chip consists of the expanding decoder (nonlinear D/A) chip with its smoothing filter, Experimental results show the circuit to meet accepted requirements.
