Web1 day ago · Our results indicate that the fast Fourier is the most efficient algorithm available for crystallographic Fourier series calculations, with efficiency increasing as one goes to larger problems. WebFourier series and Fourier transforms Let's see how our Fourier series solution to the damped, driven oscillator works by putting our previous example to work. Example: sawtooth driving force Suppose we have a driving force which is described well by a sawtooth wave, the same function that we found the Fourier series for above:
