Hi: After reading the memo of sync pulse, I still feel a little bit confused.
I use a PFB in my design. So I guess I have to include the order of PFB into the calculation. The order of PFB is 2. But there are two stage in the PFB. There are 2 taps in the second stage as well. So I set the reorder to 2 or 4? For the FFT, there are 2 order-2 reorder block in the bi_real_unscr_4x, so I recorder order should be 4. Its FFT unscrambler use an 8 order block. So its order is 8. So the sync period of FFT is 4*8*512/4 = 4096. Is this right? What I could not understand is the PFB. I use 2 order or 4? Thanks Wan
