How to design a notch filter that stops the 2 kHz ,with sampling rate 8 kHz,and plot the magnitude response,also plot pole zero locations ?

i dont know how to design a notch filter

Answer 1

[Rick Rosson]

Here's a start:

Fs = 8000;           % samples per second
Fc = 2000;           % hertz
phi = 2*pi*Fc/Fs;    % radians per sample

zeros = [ exp(j*phi) ; exp(-j*phi) ];
poles = 0.9*zeros;

...

thank you sir

[Ananya Shrivastav]

zeros = [ exp(j*phi) ; exp(-j*phi) ];

what does this mean? which formula is it?

• Design and code a simple notch filter using pole zero approach.
