I am not trying to design a filter. I just want to understand the theory of laplace transform and s-domain.I read an example from the book The Scientist and Engineer's Guide to Digital Signal Processing
I know that I can change the value of the resistor, the capacitor and the inductor . Respectively , I can change the position of the zeros and the poles. So how to design the frequency response from the position of the zeros and the poles?
For example , if I want to design a notch filter with the narrow stop band at Pi/4. How to choose the positions of the zeros and the poles? If the zeros and poles are moving around. How would them affect the frequency response(the fourier transform along the jw axies)?
