Low Pass Filter Design Using Z Transforms

02 Apr 2005 (Updated 05 Apr 2005)

This m file constructs low pass filters with -3dB bandwidths from 100Hz to >1Ghz using z transforms.

File Information
Description	This m file constructs a low pass filter using z transforms 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.The -3dB points of the filter can be set to <100Hz to >1GHz by appropiate setting of the sampling frequency(fs) and f.
MATLAB release	MATLAB 6.5 (R13)
