Fast Fourier Transforms (FFTs) are a powerful tool for evaluating the dynamic performance of analog-to-digital converters (ADCs). Numerous programs are available to process ("crunch") the output code of an ADC into its FFT components. Many of these programs are custom applications written by a C programmer.

WebWe end up with 3, 10, 8, 0. Believe it or not, we are now done. It's easy to check that 3 + 10 × 10 + 8 × 100 + 0 × 1000 = 903 which just happens to be 21 × 43, the multiplication we set out to do. Well, it looks like we did rather a lot of work, and indeed the FFT is not useful for multiplying such small numbers.
