摘要
本文研究了彩色电视光纤传输系统中的脉冲钳位电路设计,目的在于不损害全电视信号的条件下,大幅度地抑止传输系统中行同步频率以下的各种噪声和干扰。
In this paper the design of the pulse clamp Circuit in the optical fibre transmission system for colour TV is described. The purpose of it is to restrain various noises and interferences having frequency lower than the line synchronous frequency in the TV transmission system and meanwhile the composite vedio signal will not suffer from it at all.
