I have a project on filtering out frequency above 2.5 KHz. The filter should be low pass butterworth. I am confused here as there are two cutoff frequencies I need to use. 1st cutoff freq. 1KHz and 2nd cutoff freq. 5KHz.
The passband is 5 amd I/p voltage is 0-5 V.
If any one can provide me some idea about this filter design? And what kind of configuration should I use?
