IPC: H03L7/08
Filed: 1994-06-21
Abstract: PURPOSE:To eliminate the phase difference between an input signal and an output synchronizing signal by providing an input signal noise eliminating filter, a feedback noise eliminating filter and a feedback waveform shaper between a synchronizing signal generator part and a phase comparator. CONSTITUTION:A feedback noise eliminating filter 8 and feedback waveform shaper 9 are added to the output of a sine wave generator 7 to construct a feedback signal generator part. Then the output of the shaper 9 is used as the feedback signal of a phase comparator 3. The filter 8 and the shaper 9 have the same phase characteristic as a noise eliminating filter circuit 1 and a waveform shaper 2. If a signal including noises has a phase delay by the circuit 1 and the shaper 2, the phase of this signal is compared with the phase of the feedback signal by the comparator 3. Then the comparator 3 functions to eliminate the phase difference between the feedback signal and a reference signal, and the feedback signal is fed back to the shaper 9 via an LPF 4, a frequency generator 5 and a frequency divider 6. Therefore the same phase is secured between an input signal and the synchronizing signal received from the generator 7.
