WebOvershoot (when a signal crosses its limited area) and ringing are the two most important parameters of a filter’s step response. On an excellent pulse response, overshoot should be minimal. Ringing should decay asap so as not to disturb subsequent pulses. Fig. 2 : Overshoot and ringing of the signal. WebA frequency filter is an electrical circuit that alters the amplitude and sometimes phase of an electrical signal with respect to frequency. Filters are used in several electronic and telecommunications applications to emphasize signals in a particular frequency range while rejecting or suppressing those in the undesired frequency range.
