下冲（Undershoot)是怎么定义的？ - 微波EDA网

WebDuring transitions, input signals may overshoot to the voltage listed in the following table and undershoot to –2.0 V for input currents less than 100 mA and periods shorter than 20 ns. The maximum allowed overshoot duration is specified as a percentage of high time over the lifetime of the device. A DC signal is equivalent to 100% duty cycle. WebIn 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 … WebAccording to the results, compared to the other controllers, the suggested controller produced a smaller settling time, decreased undershoot, and decreased overshoot. Furthermore, PSO was also used to optimize the controller; it was compared with the proposed controller, and the superiority of DE over PSO was proved. left eye twitching and red
