Source sentences:
text: A consequence of this theorem is that the frequency function of a filter should be as smooth as possible to allow its impulse response to have a fast decay, and thereby a short width.
text: Another advantage of FIR filters is that their impulse response can be made symmetric, which implies a response in the frequency domain that has zero phase at all frequencies (not considering a finite delay), which is absolutely impossible with any IIR filter.
text: In most cases these linear filters are also time invariant (or shift invariant) in which case they can be analyzed exactly using LTI ("linear time-invariant") system theory revealing their transfer functions in the frequency domain and their impulse responses in the time domain.
text: 14-1, every linear filter has an impulse response, a step response and a frequency response.
text: For now, the important point is that all linear filters have an impulse response, even if you don't use it to implement the filter.
text: LTI filters can be completely described by their frequency response and phase response, the specification of which uniquely defines their impulse response, and vice versa.
