Hi everybody, I'm designing an analogue elliptic stopband filter to filter out more than one frequency band. I'm able to get the transfere function for each band by transfering the lowpass to bandstop using a matlab function ie. [newnum newden] = lp2bs (num,den,Wc,Bw). I'm not able to find a transfer function which will perform a filtering for more than one band. Can someone help? |
