A channel stacking system includes first and second downconverting stages, first and second analog to digital converters, and a digital switching and signal processor. The first downconverting stage includes a first downconverter circuit having an input for receiving a first RF input signal which includes a multitude of first channels. The first downconverter circuit frequency downconverts the first RF input signal to a first IF signal which includes the multitude of first channels. The first analog-to-digital converter converts the first IF signal to a first digital IF signal. The second downconverter stage includes a second downconverter circuit having an input for receiving a second RF input signal which includes a multitude of second channels. The second downconverter circuit frequency downconverts the second RF input signal to a second IF signal including said multitude of second channels. |
