Discrete Fourier Transform<br />

time and is discussed in [AHU74, Man89]. An FFT-based algorithm that multiplies two n-bit<br />

numbers in time is due to Schönhage and Strassen [SS71] and is presented in [AHU74].<br />

In recent years, wavelets have been proposed to replace Fourier transforms in filtering. See [Dau92] for<br />

an introduction to wavelets.<br />
