1) Given the specification:
Chebyshev lowpass filter
Cutoff frequency at 500 radians/second
passband ripple = 0.5dB
absolute DC gain = 1
40dB attenuation at the stop frequency of 2500 radians/second
Determine the lowpass prototype function
2) A band filter has the following specs:
Center frequency: 1500 Hz
Bandwidth: 200Hz
Chebyshev filter with a passband ripple of 1 dB
20-dB attenuation of te stopband gains at 1200 HZ and 1800 HZ.
Determine the order of teh lowpass prototype function.
