FAST TRANSFORMS Algorithms Analyses Applications by Douglas F. Elliott K. Ramamohan Rao
Fast transforms are playing an increasingly important role in applied engineering practices. No t only do they provide spectral analysis in speech, sonar, radar, and vibration detection, but also they provide bandwidth reduction in video transmission and signal filtering. Fast transforms are used directly to filter signals in the frequency domain and indirectly to design digital filters for time domain processing. They are also used for convolution evaluation and signal decomposition. Perhaps the reader can anticipate other applications, and as time passes the list of applications will doubtlessly grow.
