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.
