Honored ContributorTo be of any help can you tell me about:
your sampling frequency (of sinusoid) your fft sampling frequency do you use real and imaginary fft inputs and real/imaginary fft outputs how then do you combine real and imaginary into one signal your DAC sampling frequency(and do you correct for sinc distortion, see a today's post on that) How do you visualise spectrum? is it commercial spectrum analyser and do you have positive negative sides of spectrum?
