Hello,
A design of FFT processor on FPGA has a bit strange output, at first It was a smooth curve with two picks at the frequency of the input signal and image frequency. But once I added a few more modules to the design, all went wrong. The matlab plot looks like this.
What could potentially cause this oscillation kinda signal?
Thanks!
