VIDEO THRESHOLDER |
| 摘要 |
<p>VIDEO THRESHOLDER A two-valued digital signal is produced from an analog video signal by taking a fraction of the difference between a white peak signal and a black peak signal. The peak signals decay slowly between video pulses. A jump circuit changes one or both of the peak signals rapidly when the video signal has a certain relation to a delayed and level-shifted replica of the video signal.</p> |
