Hi, My signal is 50Hz and 175Hz (about 20% of 50Hz), Sampling 25600 samples/Sec. Implemented with 4096 pointFFT. I am getting 50Hz spectrum @8th location and expecting 175Hz at 28th location. but it is distributed to 24 & 30. other spectrum shows zero

Can any one help me on this. thanks in advance
