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...
Hello,
I am trying to implement a micro DSP with only 8 instruction
set. Can you help me with what should be the bare minimum set
required which will cater to most of the applicati...
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 + .....)

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...
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?

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...
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.
