Abstract
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.

A method of convoluting a first signal and a second signal, comprising:
- generating a multiplication signal responsive to the second signal;
- multiplying the first signal by a plurality of time shifted versions of the multiplication signal;
- integrating 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.
A method of convoluting a first signal and a second signal, comprising:
- generating a multiplication signal responsive to the second signal;
- and
- providing an output signal responsive to integrations of products of a plurality of multiplications of the first signal by 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.
A convolver, comprising:
- a plurality of multipliers adapted to multiply a first signal by a plurality of multiplication signals;
- a plurality of integrators adapted to respectively integrate products received from the plurality of multipliers;
- and
- at least one sampler adapted to provide samples from outputs of the integrators.
A method of convoluting, comprising:
- multiplying a first signal by a plurality of time finite signals, which are generated according to at least one second signal, at least a portion of at least some of the multiplications being performed concurrently;
- and
- providing an output signal by integrating the products of the multiplying over the respective lengths of the multiplied time finite signals.
