ABSTRACT:
A method of processing an electronic signal so as to facilitate the reduction of spurious signals, which includes mixing the electronic signal with a first synthesized signal of varying frequency to form a combined signal, passing the combined signal through at least one electronic component to produce an exiting signal, and mixing the exiting signal with a second synthesized signal of varying frequency which is correlated to the first synthesized signal, to form an output signal having spurious signals which are spread.
