TV transmitter circuit
Source: InternetPublisher:宋元浩 Keywords: transmitter video signal Updated: 2020/04/27
Circuit working principle: The video signal is adjusted by Rp1 and then passes through 13, and is sent to pin 16 of
the video input terminal μPC1507AC ( IC 2) of the RF modulator, and the audio signal passes through Rp2. After adjustment
, lead to R8 through R4. , C23, the RC compensation network composed of is added to
the audio input terminal 6 of the radio frequency modulator , and the pins 2 and 15 of IC 2 output the radio frequency signal modulated by the audio and video
.
