Sine Waves, Squares Waves, And The Occasional FFT
When building a square wave only odd harmonics are used as ... occurs in my Digital [Tektronix] scope in the form of a Fast Fourier Transform (FFT). For this demonstration I left the 102 pound ...

Hackaday Prize Entry: Open Source FFT Spectrum Analyzer
From there, another Python script filters the captured waveform, applies a window function, calculates the Fourier transform and plots the spectrum into a graph. With the analyzer up and running ...

Fourier Synthesis
The more general form of transferring the frequency domain to the time domain is termed the inverse Fourier transform. See: Complex Tone, Fourier Theorem, Harmonic Series, Sine Wave. Compare: Granular ...
