Analog Filter Design
No License
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
