Abstract :
An improved delta-modulation system is described which uses a delay line to obtain information about the `future¿ behaviour of the input signal. Conditions of potential slope overload are detected before the signal is encoded and the encoding pattern altered accordingly. Computer simulation results show that signal/noise ratios can be 3 dB better than for simple delta modulation.
