Abstract
PURPOSE: To improve the performance of corrections of a past error and random error occurring in transmission by forming several parity signals from a PCM signal and then by sending those signals together with an information signal.
CONSTITUTION: Both PCM signal sequences SL and SR corresponding to left and right channels from an AD converter are supplied to distributing circuit 18, where the both are divided into three channels, for example. At every time of the mode- by-mode supply of each PCM signal sequence to adder A1, a parity signal sequence SP is formed and then passed through a delay circuit of word time 96 to generate delayed parity signal sequence SP1. In the same way, adder A2 generates parity signal SS. Then, these PCM signals SL0WSR112, parity signals SP1 and SS1, and pointer signal SQ are all supplied to mixer circuit 22, where they are made into a one-channel signal sequence, which is supplied to time-axis compression circuit 23. Consequently, a PCM signal transmitting method with high correction performance can be realized.
