Abstract
The transmission process comprises a coding of the sound signal consisting of converting it into words of n bits at a frequency double the line frequency and during each synchronization pulse transmitting four words of n bits corresponding to different samples, which introduces a redundancy of two and a decorrelation between the different samples. The process involves a decoding operation consisting of comparing the two representations of the sample transmitted during the two synchronization pulses and selecting one representation for each sample as a function of the result of the comparison.
