雙絞線在傳輸視頻上和同軸線纜相比有着很多的優點,因此很多人在遠距離傳輸視頻信號事都非常熱衷於選購雙絞線作為傳輸介質。那麼,採用雙絞線傳輸視頻信號的原理是如何?

雙絞線傳輸視頻信號的原理

1、雙絞線是一種平衡傳輸方式的線纜,具有很強的抗干擾能力,所以使用雙絞線傳輸視頻信號,必須將視頻信號轉換成平衡信號。

2、使用雙絞線代替視頻線傳輸視頻信號,只需要在線纜的前、後端均加進平衡/非平衡轉換器即可。

3、轉換器只起到平衡/非平衡轉換的作用,不會帶來新的失真,也不會產生噪聲,但對信號有一定程度上的衰減。

4、雙絞線接收器,起到放大、補償的作用,一般有二個可調的電位器,可根據實際情況調節放大器的放大增益以及對高頻分量的補償量。

Twisted pair transmission video signal principle

1, twisted pair is a balanced transmission cable, has a strong anti-interference ability, so the use of twisted pair transmission of video signals, the video signal must be converted to a balanced signal.

2, the use of twisted pair instead of video cable to transmit video signals, only the front and back of the cable are added to balance / unbalance converter.

3, the converter only play a balanced / unbalanced conversion, will not bring new distortion, it will not produce noise, but the signal has a certain degree of attenuation.

4, twisted-pair receiver, play a role in amplification, compensation, generally two adjustable potentiometer, according to the actual situation to adjust the amplifier gain and the high-frequency component of the compensation amount.
