A DSP algorithm for frequency analysis

Posted: 01 Feb 2004     Print Version  Bookmark and Share

Keywords:Chirp-Z transform  spectrum-analysis algorithm  DSP 

Engineers working in the field of digital signal processing often use the fast Fourier transform (FFT) algorithm to detect tones, frequencies, signatures, and other events. In specific situations, however, other algorithms may actually work better than the FFT. Knowing when to use what algorithm can help you improve the system you're working on.
