Abstract
Abstract A satellite TV system including a plurality of channel strips each including a tuner and a modulator matched to each other. The tuner selects the particular satellite signal and the modulator selects the particular channel on the TV. Both tuner and modulator circuits include a divide-by-two component which permits use of lower cost electronic components while producing high quality TV pictures or other outputs. Each channel strip is in the form of a plug-in module. A control box houses all of the plug-in channel strips and the other electronics.
