Answered: INFOZOU on 10 Oct 2016

I currently have data of frequency vs voltage and time vs voltage for a sine wave with a frequency of 700 Hz, amplitude of 5 volts. A sampling frequency of 25 kHz and a bipolar range of +- 10 volts. I am being asked to create a Nyquist frequency folding diagram with the harmonics of it clearly plotting. I am not sure how to create this. I am fairly new to matlab.

Beside matlab, do you have the formulas to get your data to plot?
