Abstract
A convolution method and apparatus of time domain convolving an input signal with a second signal is disclosed comprising the steps of; dividing the second signal into a series of segments; determining a magnitude envelope for each of the segments; scaling the signal values within each segments relative to the envelope to produce corresponding segment scaled signal values; multiplying the segment scaled values by a corresponding input signal value to produce corresponding segment output values; scaling the segment output values by a segment scale factor to produce corresponding scaled segment outputs; and adding the scaled segment output to produce a time domain output.
