Title: Algorithm to calculate SNR,SINAD from FFT
Post by vivekrc on Nov 15^th, 2004, 1:55pm

Hi,

In Verilog AMS, I have written an ideal four bit ADC code . The bits and the analog signal value are written to a file(4bitideal.dat) .I am calling this 4bitideal.dat file in Matlab.
I am interested in an algorithm which calculates the Signal to noise ratio, Signal to noise plus distortion , spurious free dynamic range, total harmonic distortion from an FFT plot. FFT plot of a sine wave was obtained by reading the data from a file computed by Verilog AMS in Matlab.
Thanks
Vivek
