ABSTRACT:
A combined encoder/decoder (transcoder) for multiplexed pulse code modulation/delta modulation conversions utilizes a single set of arithmetic elements to perform both the encoding and decoding functions. An interpolator, a magnitude comparator and an integrator, being the prime arithmetic units, are realigned by switching their serial positions to perform the encoding and decoding functions.
