METHOD AND APPARATUS OF CONVOLVING SIGNALS

A method of convoluting a first signal (32) and a second signal. The method includes generating a multiplication signal responsive to the second signal, multiplying (34) the first signal by a plurality of time shifted versions of the multiplication signal, integrating (38) the products of the multiplying of the first signal and the plurality of time shifted versions of the multiplication signal, the integrations being performed over a time period longer than the time difference between at least two of the time shifted versions, and providing an output signal based on the integrations of the products.
