Understanding the workings of Vertical Deflection
Vertical deflection parts, serves to provide a sawtooth current to the vertical deflection coil so that horizontal lines are generated by applying localized horizontal deflection from the top of the screen and moves towards the bottom of the screen. Sweeping PAL system has a vertical frequency of 50 Hz and 60 Hz NTSC system. Vertical deflection circuit there are several variation, is in contrast to the horizontal deflection circuit on television almost all the same. Broadly , the vertical deflection section comprises: Yoke Deflection Vertical oscillator (vertical countdown) Ramp generator Vertical amplifier drive Vertical amplifier-out Pum-up (flyback generator) Feedback circuit Vertical deflection coil Countdown vertical as the vertical oscillator . Vertical count-down got input from the horizontal frequency count-down and divide in order to obtain the vertical frequency. In this section there is a circuit called a "vertical window-counter" which serves to automatically ad...
