Resonance

Resonance. January 28, 2010. Last Time. We discussed the difference between sine waves and complex waves. Complex waves can always be understood as combinations of different sine waves. The sine waves that combine to form a complex wave are known as harmonics .

The Fast Fourier transform (FFT)

The Fast Fourier transform (FFT). The time taken to evaluate a DFT on a digital computer depends principally on the number of multiplications involved(the slowest operations). With the DFT, this number is directly related to , where N is the length of the transform .
