补充资料:限幅电路
限幅电路 clipping circuit 能按限定的范围削平信号电压波幅的电路。又称限幅器、削波器。限幅电路常用于:①整形,如削去输出波形顶部或底部的干扰。②波形变换,如将输出信号中的正脉冲削去,只留下其中的负脉冲。③过压保护,如强的输出信号或干扰有可能损坏某个部件时,可在这个部件前接入限幅电路。限幅电路按功能分为上限限幅电路、下限限幅电路和双向限幅电路3种 。在上限限幅电路中,当输入信号电压低于某一事先设计好的上限电压时,输出电压将随输入电压而增减;但当输入电压达到或超过上限电压时,输出电压将保持为一个固定值,不再随输入电压而变,这样,信号幅度即在输出端受到限制。同样,下限限幅电路在输入电压低于某一下限电平时产生限幅作用。双向限幅电路则在输入电压过高或过低的两个方向上均产生限幅作用。 |
