X(ejw) X2(ejw)X1(ejw) 0 w Need of Time-domain And Frequency-Domain Aspects of Non- ideal filters spectra of signals overlap slightly We may wish to trade off the fidelity with which the filter preserves one of the signals A filter with a gradual transition from passband to stopband when filtering the superposition of signals with overlapping spectra prefer Nonideal filters are of considerable practical importance

- 6. Define the Time-domain And Frequency-domain Aspects Of Nonideal Filters? Time-Domain Behavior of Nonideal Filters Parameters characterizing the nature of ringing Oscillator behavior i.e. ringing is often of importance The overshoot ∆ of the final value of the step response Ringing frequency wr Settling time ts the time required for the step response to settle within a specified tolerance
