IPC: H04N5/21
Filed: 1983-07-20
Abstract: PURPOSE:To decrease occurrence of buzz due to Nyquist slope by generating no phase modulation of the local oscillator due to amplitude modulation of the video carrier. CONSTITUTION:Output from the video IF amplifier 3 has amplified modulation and the phase of the video carrier at the synchronizing signal period t1 becomes different from the phase of the video carrier at the video signal period t2 due to passing the filter 2 having Nyquist slope, however, the following synchronizing signal period t3 has the same amplitude as the synchronizing signal period t1, and therefore, the period t3 has the same phase as the period t1. Therefore, output of the video carrier which always has the same phase, and the local oscillator 4 can be compared by sampling video carriers of the synchronizing signal periods t1 and t2 by the gate pulse b, and video detection can be executed by locking the video carrier which always has the constant phase with the local oscillator 4. As a result, occurrence of the buzz due to Nyquist slope can be reduced.
