EXP 5. ANALOG AND DIGITAL BUTTERWORTH FILTER DESIGN
If observed parameter values and actual values are notmatching then the order has to be increase
Magnitude spectrum is monotonic in both passband and stopband .
IIM method works well for LPF but could not be used for HPF.
After execution , I found that for both low pass and high pass filter, poles lie inside the unit circle, hence both the filters are stable. As order increases stability increases.

Why do we first implement analog filter and then go for digital filter?why not directly to digital one?
ReplyDeleteIs IIR filter stable ?
