Abstract
A deflection circuit for a video apparatus is capable of operating at different horizontal rate frequencies in response to the incoming video information rate. In one embodiment, the deflection oscillator input voltage is varied in a cyclical manner to vary the oscillator frequency. When the oscillator frequency corresponds to the frequency of the incoming video information, the input voltage is maintained to maintain the desired oscillator frequency. In an alternate embodiment, a frequency to voltage converter generates the desired oscillator input voltage in response to the incoming video information rate.
