摘要: A power supply and deflection circuit for a video monitor provides multiple horizontal scan rates. switch is used to select the desired rate. Operation of determines proper operating voltage level circuit. zener diode high or low signal in response determined voltage. The oscillator frequency value S-shaping capacitor signal. operation switch, therefore, necessary parameter changes each rates selected.
