ABSTRACT:
An apparatus and a method for multiplying two time varying signals to produce a four quadrant, multiplied signal is provided. In one embodiment of the present invention, an apparatus for multiplying a first signal with a second signal includes an analog-to-digital converter that provides a first digital signal representative of the first signal, a first modulator that provides a first modulated signal representative of the second signal, a multiplier that multiplies the first digital signal by the first modulated signal and provides a second digital signal representative of a result of a multiplication of the first signal and the second signal, and a first filter having an input to receive the second digital signal and having an output that provides the multiplied signal.
