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 |
