摘要 |
<p>A keying pulse generator for a color television burst gate provides a gutting pulse in response to horizontal synchronizing pulses when present and in response to horizontal retrace pulses when sync pulses are absent. A timing circuit is provided to maintain a constant width keying pulse independent of video signal condition and receiver operating characteristics.</p> |
