29. A method of down-converting a first signal to a second signal, comprising the steps of:
(1) receiving the first signal;
(2) sampling the first signal over aperture periods to transfer energy from the first signal;
(3) integrating the energy over the aperture periods; and
(4) generating the second signal from the integrated energy.
