Abstract
A method and apparatus for extending the dynamic range of an integer or fixed-point Fast Fourier Transform ('FFT') system that may be used in communications devices such as ADSL modems. The disclosed FFT system utilizes a shift control module to increase the effective dynamic range of the FFT implementation by selectively choosing at least one stage of an FFT butterfly implementation in which the outputs of the butterfly stage are not divided to otherwise avoid overflow problems.
