Abstract
PURPOSE: To prevent interference between fly-back pulses and horizontal synchronizing signals by connecting a diode to the capacitor of the saw tooth wave voltage supply side.
CONSTITUTION: A horizontal AFC circuit is constituted by connecting newly a series circuit of capacitor 18 and diode 19 in parallel to diode 6. By this constitution, interference components of a saw tooth wave appearing at point A are reduced by forward drop voltage components of diode 19, and the trailing edge of the horizontal synchronizing signal at point A becomes sharp. Consequently, the waveform of burst gate pulses at point B obtained by differentiating the signal by a differentiating circuit consisting of capacitor 20 and coil 21 has a large amplitude and a narrow pulse width, so that the burst signal can be extracted accurately. Further, since the circuit which makes the trailing edge of the horizontal synchronizing signal sharp can be constituted only by providing one diode, the bad influence upon the horizontal synchronizing signal can be prevented with the simple constitution.
