fft code example
What is FFT command?
A fast Fourier transform (FFT) is a highly optimized implementation of the discrete Fourier transform (DFT), which convert discrete signals from the time domain to the frequency domain.
FFT computations provide information about the frequency content, phase, and other properties of the signal.How to calculate FFT?
The formula to calculate FTT is: (Units produced-defective units)/units produced.
