1. A method for down-converting a carrier signal to a lower frequency signal, comprising the steps of:

  • (1) receiving a carrier signal;

    (2) transferring non-negligible amounts of energy from the carrier signal, at an aliasing rate that is substantially equal to a frequency of the carrier signal plus or minus frequency of the lower frequency signal, divided by n, where n represents a harmonic or sub-harmonic of the carrier signal; and

    (3) generating a lower frequency signal from the transferred energy.
