How do I design a bandpass filter with Chebyshev characteristics?
My tutor gave me following specifications:
Bandpass
Chebyshev 2nd order with multifeedback
highpass, low pass= 2kHz/2kHz
ripple 1dB
I calculated the transfer function (the result is sth like this **broken link removed**)
but it is not possible to compare the coefficient. (because of the degree of the numerator).
My next idee was to apply "lowpass to bandpass transformation" ie transform a 1st order lowpass with Chebyshev characteristics to a bandpass.
But would that be the correct way? (It's necessary that the result is a band-pass with 2nd order, multi feedback bandpass and I don't know whether the circuit would be multi feedback)
What would be/ your approach for this problem?
thanks
