Here is another way to think about it. If you start with simple 2-pole filter time
domain equation:
y[n] = b0x[n] + b1x[n-1] + b2x[n-2] +a1y[n-1] + a2y[n-2]
Let...

Dear Jeff
I did normalize and quantize the sos to Q15. But the thing I am not getting any difference in the filtered output of non quantized and quantized coefficients. I checked ...

Scaling all coefficients changes the overall filter gain, but the not the shape of

hi everyone
I am working on IIR filter designing. I am gonna use the function iircas51. I am designing the filter using matlab and I have a question regarding converion of filter ...
