SYNCHRONIZING SIGNAL DETECTING APPARATUS |
摘要 |
<p>SYNCHRONIZATION SIGNAL DETECTING CIRCUIT A synchronizing signal detecting circuit for synchronizing digital data receiving equipment is disclosed. Digital signals consisting of data and synchronizing signals obtained by repeating a predetermined pulse pattern many times are fed to a shift register in succession in synchronism with clock pulses. A gate circuit connected to the shift register detects the synchronization pulse pattern. A detector circuit detects a duration period of a coincidence signal which is the output of the gate circuit, and outputs a synchronous detection signal when the duration period of the coincidence signal exceeds the predetermined value. This synchronizing signal detecting circuit can detect synchronizing signals even when data errors are produced to some extent. - 0 - 0</p> |
