Abstract

Known are transmission systems for stereophonic signals. In a well-known stereophonic transmission system, left-hand channel and right hand channel stereo signals are composed to a combined signal using balanced modulator and a pilot tone for forming a difference signal. The combined signal is obtained by combining a socalled summing signal, the pilot tone, and the difference signal. Such a stereo transmission system is complicated as regards coding and decoding of the left and right stereo signals. Besides, the phase relationship between the pilot tone frequency and the sub-carrier is very critical. Also, such a system requires relatively complicated and time consuming adjustment procedures. A simple and effective stereophonic transmission system (1) is proposed, in which the transmitter (2) alternatively encodes opposite block periods of a block signal with samples of the left-hand channel signal (Lin) and the right-hand channel signal (Rin). At receiver side the left-hand and right-hand stereo signals are decoded from the encoded block signal by alternative integration and peak detection of positive and negative received pulses, the pulse widths of the received pulses corresponding to amplitudes of the transmitted samples. When detecting the pulses for one stereophonic channel, the corresponding other stereophonic channel is blocked.
