So you all know how to get the magnitude response of a Z-transform!
1- replace Z=exp(iƟ) then |X(Ɵ)| = √ a^2+ b^2
Also there is another way
2-|X(Ɵ)|^2 = X(Ɵ) x x(Ɵ*)
So you multiply frequency response its conjugate!
The answer is almost identical BUT one of them is squared!
So if they ask me to find a magnitude response or find the 3dB Ɵ Which one should I choose?
Cheers!
