FIELD: electricity.
SUBSTANCE: method of differential pulse-code modulation - demodulation of signals consisting in quantisation of error signals, their coding and recovery of quantised error signals after transfer in a channel, at the same time for each interval of time [ti, ti+1], ti+1>ti, i=0, 1, 2, … forecasting of spline-approximation coefficients of an information signal is done, they are confirmed by recovered quantised error signals, a recovered information signal is generated by confirmed estimates of coefficients in the form of a continuous spline process.
EFFECT: improved noise immunity of signals transfer and reception.
