1. A method for down-converting an electromagnetic signal, comprising the steps of:

  • (1) performing with a finite time integrating module a finite time integrating operation on a portion of a carrier signal;

    (2) accumulating the result of the finite time integrating operation of step (1); and

    (3) repeating steps (1) and (2) for additional portions of the carrier signal, whereby the accumulation results form a down-converted signal.
