TELEVISION VIDEO SIGNAL DETECTOR |
摘要 |
<p>TITLE OF THE INVENTION: Television Video Signal Detector The video IF signal is applied to a carrier amplifier so that the signal is amplified and limited in amplitude and consequently only the carrier can be derived. The video IF signal is also amplified by a linear amplifier and compensated by a phase compensation circuit in such a way that the relative phase difference between the outputs from the carrier amplifier and linear amplifier can be eliminated. The outputs from the carrier amplifier and linear amplifier are applied to a synchronous detector, whereby the television video signal without any distortion can be derived.</p> |
