2-D digital filtering - Appalayagari Sreedhar - Jan 31 6:26:00 2003



Dear all,

I am working on the 2-D fir filtering,

i need to calculate the passband ripple and stopband attenuation for the 2-D fir
filtering case using matlab,

for 1 - D i can use max(H) which will give me the passband ripple

and i can calculate the stopband ripple as min(H) and i can subsequently
calculate stopband attenuation, but i am confused with the 2-D case.

does anyone worked on this and know about this, please mail me with the matlab
code along with an example problem(if possible), i really need this, i am
designing the 2-D filter but i cannot calculate them, i will be waiting for all
your great help.

regds,sree
