The weighting function for the stop-band increases exponentially with frequency so that the …
WebWelcome John J.B. Allen, Ph.D. WebA finite impulse response (FIR) filter is a type of a discrete-time filter. The impulse response, the filter's response to a Kronecker delta input, is finite because it settles to zero in a finite number of sample intervals. A Finite Impulse Response Digital Filter, usually consisting only of Zeros (no Poles), and generally implemented by a ...
