ABSTRACT:
Delta encoding circuitry of the type in which a digitally-encoded signal is determined by the difference between a present value of an input signal and a reconstructed signal representative of a past value of said input signal. The occurrence of a high or a low state in the digitally-encoded signal corresponds to an incremental change in the input signal of an amount dependent upon a reference signal determined from said digitally-encoded signal. The reference signal is increased by a positive-feedback circuit upon detection of one or more consecutive repetitions of the same digital state in the digitally-encoded signal.
