Abstract
A system for single path processing identical, substantially identical, close or interfering frequencies with a single analog-to-digital converter. The system receives a plurality of input signals at various frequencies and front end circuits filter out first and second frequencies. A mixer and a front end oscillator are in communication with one of the front end circuits for mixing a front end frequency with one of the first and second frequencies prior to the analog-to-digital converter. A summer combines the output of the mixer with the output of one of the front end circuits. An analog-to-digital converter is connected to the summer for converting the analog input signal to a digital output signal. The first and second frequencies may be separately processed after they have been combined, even if they were identical frequencies.
