Analog Filter Design

Analog filter design using Butterworth & Chebyshev approximations.

This program is used for Analog Filter Design.

This program designs a filter, computes the filter order, plots the impulse & step response, and computes the transfer function.

For Butterworth & Chebyshev Approximations:

Sample Run:
>> filters

Enter the Approximation method You will use
Enter (b) for Butterworth Approximation or (c) for Chebyshev : b

You choose Butterworth Approximation :
Enter (o) if You know the order or (d) for a filter design : d

Enter the normalized Rejection frequency : 2

Enter the Attenuation value at this frequency in dB : 30

The order of the filter is 5
Transfer function:
1
