AB  - This paper presents a design for an all digital two band sub-band coder to provide "commentary quality" speech and music over a single slot in a Tl carrier system. It provides a 7 kHz bandwidth at a transmission rate of 56 kb/s with no noticeable distortions or noise under normal "casual listening" environments. It provides a better quality and a more robust performance than a previously discussed analog coder. The design incorporates a number of new digital techniques including quadrature mirror filtering, and high quality A/D and D/A conversion circuits.
