Hi all! I am try to find out the low-pass filter cut-off frequency. I input an impluse to filter,then got the impulse response. But,I have a problem about the impulse size. when I used one pixel,the result is nothing! so,I am try using different impulse size pixels to filter, then I got many different results. I am very confused about this problem , Can anyone tell me that I should use ...
