Band Pass Filter Design Using Z Transforms

Constructs two pole two zero band pass filters with center frequencies from 100Hz to >4G.

This m file constructs a two pole two zero bandpass filter using the z domain transfer function and analyzes the characteristics of the filter such as frequency response and phase using the Matlab filter function with input vector x to get output y=filter(b,a,x). Frequency domain plots are also provided to analyze the bandpass filter.
