Most modern scopes can compute the Fourier transform of a signal, as in the following screen capture. The bottom trace is a simple 10 MHz sine wave. Above it is the Fourier transform. Unlike a normal ...

If you’re a regular reader we’re sure you’ve heard of the Fourier Series (often discussed as FFT or Fast Fourier Transform), but ... into combinations of simple sine or cosine equations ...

The construction of a PERIODIC signal on the basis of Fourier coefficients which give the AMPLITUDE and PHASE angle of each component sine wave HARMONIC. These coefficients are obtained through ...
