Abstract: In a digital recording-playback technique, a ring counter is utilized in playback mode to insure that bits have not been dropped or spurious noise signals recorded. If the correct number of signals have been recorded in a word preceding a synchronizing signal, signals are obtained from two adjacent stages of the ring counter that permit the synchronizing signal to open a transfer gate from a shift register to a display register. If the correct number of signals has not been received, transfer is inhibited.
