Abstract
A transmission system which on the transmission side comprises a pulse-code modulation device, which is adapted for the pulse code conversion of consecutive minimum groups of two signal, elements of the information signal, the pulse code modulation device comprises a shape encoder, which in each group interval, encodes by a pulse code a normalized-amplitude shape of the signal variation of the two signal elements, and furthermore comprises an amplitude encoder, which in each group interval, encodes an associated amplitude value by a pulse code. The receiver comprises a multiplier stage for multiplication of the normalized-amplitude shape, which is transmitted in pulse code, in each group interval, by the associated amplitude value.
