그것 기능 is to combine video signals (VIDEO) and The audio signal (AUDIO) is modulated into a stable high-frequency radio frequency oscillation signal, the video is AM modulation, and the audio is FM modulation.
Digital TV modulators are widely used in the transformation of digital cable TV front-ends to modulate audio and video signals into radio frequency signals. The input audio and video signals can be continuously adjusted through the external adjustment knob, allowing the input of 0.7~1.4V video signal source signal and 0.775V±10dB audio signal. Under normal frequency deviation conditions, the modulator can 또한 be 연속적으로 조정된 외부적으로. 출력 이미지 is fine. 제품 채택 주파수 합성 기술 with high frequency stability.
