THE FASTEST FOURIER TRANSFORM IN THE WEST

THE FASTEST FOURIER TRANSFORM IN THE WEST

Arduino News / By

An interesting aspect of time-varying waveforms is that by using a trick called a Fourier Transform (FT), they can be represented as the sum of their underlying frequencies. This mathematical insight is extremely helpful when processing signals digitally, and allows a simpler way to implement frequency-dependent filtration in a digital system. [klafyvel] needed this capability
