    Abstract: A differential coding system is proposed which, when the slope of the message signal to be coded is large, accelerates the production of the output of a quantizer which is used to encode the message signal. A digital coder and elastic store are interposed between the quantizer and transmission line to insure that the digitally coded signal is transmitted at a desired line rate while the production of those digital signals may be significantly greater than the line rate. A decoder is utilized at the receiver which functions in the inverse manner and enables the coded message signal to be decoded.
