Web在电子学中，过冲是指，从一个值转变到另一个值时，任何参数的瞬时值超过它的最终（稳态）值。过冲在放大器的输出信号中有重要的意义。惯例: 过冲发生于瞬时值超过最终值。当瞬时值低于最终值时，也称为“下冲（undershoot）”。一般电路设计，多半會使上升时间（英语： Rise time ）最小 ... In signal processing, control theory, electronics, and mathematics, overshoot is the occurrence of a signal or function exceeding its target. Undershoot is the same phenomenon in the opposite direction. It arises especially in the step response of bandlimited systems such as low-pass filters. It is often followed by ringing, and at times conflated with the latter.
