hi..

i made mistake in post

in the last part

*We know w0 = 2*pi*f0/Fs

*-what is the value of pi(180 0r 3.14)

*-w0 is the angular representation of requency i think it will be 180

*-then in above value of alpha will be zero always.

*-it means Q doesnt have any importantce in filter design

*-please suggest a good book which describe in detail about filter design

what i meant is in the expresion w0=2*pi*f0

value of pi 1s 180 or 3.14.

with regards
