You can use this applet to get impulse response coefficients and plot the
frequency response of maximally flat filters of any type!

The filters are identical to
those proposed by H. Baher. You need to download and install
JAVA2 Runtime Environment .

For the meaning of parameters refer to
"Universal maximally flat lowpass
FIR systems, IEEE Tans. SP, pp. 1956-1964, 2000".

It may take a while to compute coefficients for orders higher than 10,
so be patient. Try the applet with N=2, K=1, and d=0/1 to get the idea.

You may get incorrect values for certain combinations of the parameters.
This happens when the number of digits required to represent the
coefficients is large.
