ABSTRACT:
A device for processing a signal coded by means of delta modulation with a sampling rate F, comprises an analyzer for the delta modulation signal for successively forming data each of which characterizes the number of binary elements of two successive trains formed by different binary elements, each train comprising a binary element or a series of identical binary elements, a store in which said data are entered, and, finally, means for forming from the data entered into the store a sequence of binary elements composed of .lambda. times the two above-mentioned trains with a frequency of the binary elements equal to 2.lambda.F, .lambda. being an integer exceeding one. The device supplies a digital signal, which, after decoding, constitutes an excellent approximation of the analog signal which had been coded.
