What is the general formula that represent the phase of the poles of transfer function of normalized low pass Butterworth filter of order N?(a) \(\frac{π}{N} k+\frac{π}{2N}\) k=0,1,2…N-1(b) \(\frac{π}{N} k+\frac{π}{2N}+\frac{π}{2}\) k=0,1,2…2N-1(c) \(\frac{π}{N} k+\frac{π}{2N}+\frac{π}{2}\) k=0,1,2…N-1(d) \(\frac{π}{N} k+\frac{π}{2N}\) k=0,1,2…2N-1I got this question by my college director while I was bunking the class.Origin of the question is Butterworth Filters in division Digital Filters Design of Digital Signal Processing |
