fftTutorial

Python scripts and documents demonstrating FFT, power spectra, and cross spectra. NFFTFSdemo.py does not require any inputs. Simply run the program. It generates a graph of 4 sine curves and the result of 4 ffts. The 4 graphs are supposed to demonstrate how changing the NFFT and FS affects the psd function Example1.py gives the program needed to generate the first example. It should help teach students basic plotting and the PSD function.
