poles and zeros

Started by smita shekar November 17, 2003
Hi,

Wanna know how do you find the magnitude response of an FIR filter from the
the pole-zero plot in the Z-plane...i know that at poles the magnitude is
maximum and itz minimum at zeros...but how do you plot the response when
there are a large number of poles and zeros........Please let me know if
there are any links or references that give more information on poles and
zeros....

thanks.,
smita.
