Abstract
In an error correction circuit of the type in which a received audio signal is passed to the error correction output when no error is detected and wherein a substitute signal, e.g. either a previous value of the received audio signal or a muting signal, is provided to the error correction circuit output when an error is detected in the received audio signal, complementary gain control circuits are employed to gradually fade in the newly selected signal while gradually fading out the previously selected signal to eliminate undesirable clicking noise.
