A new monolithic LSI product has recently been developed for the telecommunications market. The device is a coding-decoding circuit called a codec that converts analog voice signals into digital bit streams and back to analog form. Its primary application is in telephone channel banks, where its low cost makes per channel coding and decoding of voice signals economically feasible. In this work such a codec set is used in conjunction with two hybrid filters as the main components of a single channel voice transmission system. The operation and the performance of this system are presented. Author
