ABSTRACT:
A process for regenerating a periodic signal creates two signals. The first ignal provides for the detection of a periodic signal for a short time preceding the theoretical timing position of the periodic signal. The second signal is transmitted a very short time after the theoretical timing position of the periodic signal and serves as a substitute periodic signal, when the periodic signal has not been detected prior to a transmission of the second signal. The circuit, used to receive broadcasted digital data, is comprised of a counter (L), a D flip-flop (B1) and a clock (CLX) having a frequency which is equal to a multiple of the data bit rate which is to be received. The counter (L) has an initializing input connected to the Q output of the flip-flop (B1). It has two outputs (X, Y) corresponding to the transmissions of the first and second signals. The first output (X) is connected to the "1" setting input while the second output is connected to the "0" resetting input of flip-flop (B1), having a D input which is connected to a "0" level voltage. The clock input receives the periodic signal.
