Tim, Under what conditions can a IIR be approximated by a non-linear phase FIR? Do all pratically realizable stable IIR's have their non-linear phase FIR as counterpart? If I f...Re: FIR and IIR?

The Transfer function in matlab and octave are modelled with numerator and denominator coefficients being all positives. H(z) = (bo + b1 z^-1 + b2 z^-2 .....)/(a0 + a1 z^-1 + a2 z^-2 + .....) S...Re: Simple question about calculating difference equation coefficients

just like half band filters are ther 1/3 band filters too?

bharat pathak - 2011-02-02 09:16:00
Hello, Half band filters are good for interpolation and decimation by 2 as they have alternating 0's as their coefficients. Is there something like 1/3rd band filters for doing i...just like half band filters are ther 1/3 band filters too?

how to find the amount of transients in minimum phase FIR filters.

bharat pathak - 2011-02-02 09:11:00
Hello, Minimum phase FIR filters have group delay distortion. In such cases how can one arrive at the amount of transients such designs can have? Regards Bharat ...how to find the amount of transients in minimum phase FIR filters.

Re: FFT rounding errors in fixed vs floating point
0

bharat pathak - 2011-01-30 21:38:00
My thought process is it will depend on number of points used for FFT. So best way is to measure the SNR after the FFT is done and see it is able to measure 24 bit input numbers. Else fractional bit...Re: FFT rounding errors in fixed vs floating point

Re: Droup delay in FIR implementation
0

bharat pathak - 2011-01-25 11:30:00
Dhaval, Group delay (in case of FIR filters) is the designer introduced delay to make the filter causal. In case of your example 2 tap filter the group delay is 0.5 samples. ...Re: Droup delay in FIR implementation
