1. A method, comprising: converting a frequency spectrum of a segment of an input signal and a frequency spectrum of a corresponding segment of an impulse response function from a floating point data format to a fixed point integer data format; multiplying the converted frequency spectrum of the segment of the input signal with the converted frequency spectrum of the corresponding segment of the impulse response function; and generating a desired convolved signal corresponding to a convolution involving the segment of the input signal and the corresponding segment of the impulse response function in the time domain using multiplication results from said multiplying.
