What's the characteristic of this kind filter?
And is it reasonable to make a filter like this?
Thanks,
 

zero means the ascending of the spectrum from the zero to inifinty.
So if you add a zeros at zeros ,that means you want to emphasis the part of the high frequancy band part of the signal.
 

Can we design a low pass filter with zeros at Z=0?
Thank you,
 

Of course,you can add all zeros in your design .
Because zeros can't cause the stability problem.
 

what type of filter u r talking abt? I mean IIR or FIR

thnx

purna
 

I designed the switched-capacitor filter to implement the
Z-domain transfer function.
