Thanks @ricardas, but i couldn’t make it to work.
From the image #3 of my first post (GFIR 2 and 3 bypassed), if Length=1 for GFIR1, then I have 10 taps. I click in the coefficients button and into the “coefficient count” field (when it’s always in 40 when I click in the button) I put 10, and fill with the coefficients: 1,0,0,0,0,0,0,0,0,0. When I click “Ok” I obtain the same signal as in the image #2. This only works in TxTSP.
If i click again in the coefficients button, the coefficient count field it’s on 40 again and I have all the 40 coefficients fields to be filled.
I’ve tried with the filter 0,0,0,0,1,0,0,0,0,0 (setting Length = 1 and coefficient count =10) with the same results, but when I click again on the coefficients button, the tap filled with the number moved to a random position instead of being in the position #5.
Another thing that happen is: if I set Length in 7, fill the first coefficient with 1 and the rest with zeros and I click in Ok, the Length automatically sets in 1 (both in TxTSP and RxTSP).
