Abstract

PURPOSE:To enable synchronizing detection with reliability, by using a signal train system consisting of an accessory signal, synchronizing signal and effective data and establishing the detection of synchronism with the logical product between the synchronizing signal and the accessory signal. CONSTITUTION:After an input signal DATA.IN is sequentially shifted at a shift register 1, it is given to a gate 6, and the gate 6 is closed initially and the input signal is temporarily interrupted. Accessory signal and synchronizing signal in the input signal are detected at an accessory signal detecting circuit 2 and a synchronizing signal detecting circuit 3 during the operation and the detection of synchronizm is established with an AND circuit 4. The gate circuit 6 is opened in accordance with the AND output SYNC.D and only an effective data DATA in the input signal is transmitted externally. Thus, the misdetection of synchronizm can be avoided due to noise in comparison with the method of detection of synchronizing signals only conventionally and reliable synchronism detection can be made.
