ABSTRACT:
Conventional delta modulation techniques ignore information contained in the input signal which may be used advantageously in the encoding process. Improved delta modulation methods are disclosed which reduce bit rate and enhance error performance by partitioning the input signal into variable-length segments determined by preselected characteristics of the signal. Within each segment, iterative encoding is employed to develop the bit stream representing the encoded input signal. One particular partitioning method employs positive and negative signal peaks to establish segment boundaries and the encoding process is aided by the gradient of the signal within each segment.
