Hi forum,
How to calculate FFT core SQNR?
Sounds very easy but seems it is not.
I have a Verilog RTL core for FFT.
I have a very accurate reference model for FFT.
Let's assume that my RTL core outputs are R0, R1, R2.......Rn.
And reference model outputs are M0, M1, M2.......Mn.
Having these samples how can I calculate my FFT core SQNR.
