Abstract :
An echo suppressor that is composed solely of digital logic circuits and based on a digital voice detector [1] has been designed. The unit is simple and requires no adjustment. Its basic application is to the SPADE [2] PCM channel, although it can be adapted to work with other systems. Results of initial subjective tests are included.
