Abstract
Edge busyness in delta modulation (AM) is analyzed theoretically and a method of reducing edge busyness is presented. By assuming a simple model for quantizing error waveforms, a theoretical signal-to-edge noise ratio is derived as a function of signal slope. It is shown that more than 10-dB edge-busyness reduction can be achieved by limiting input signal slope to about 80 percent of the
overload slope prior to
. The performance is verified through computer simulation and experimentation.
