Let h(t) and H (s) be the impulse response and system function of a stable and causal
system, respectively. H (s) is rational and has a pole at s = 2, and it does not have a
zero at the origin. Other
Band Stop Filters
Band-stop filters:
Also called band-elimination, band-reject, or notch filters, this kind of filter passes all
frequencies above and below a particular range set by the component values. Not
surprisingly, it can be made out of a low-pass

Band Pass Filter
Band-pass filters:
There are applications where a particular band, or spread, or frequencies need to be
filtered from a wider range of mixed signals. Filter circuits can be designed to accomplish
this task by combining the properties of l

High Pass Filters
High-pass filters:
A high-pass filter's task is just the opposite of a low-pass filter: to offer easy passage of a
high-frequency signal and difficult passage to a low-frequency signal. As one might exp
