Apparatus and Method for Processing Signals in a Multi-Channel Receiver

Signal processing apparatus suitable for performing front-end signal processing in a multi-channel receiving device such as a multi-channel television signal receiver utilizes a cost-effective and scaleable architecture. According to an exemplary embodiment, the signal processing apparatus includes an RF signal source operative to generate first and second RF signals responsive to user channel selection. A first IF generator is operative to generate a first IF signal corresponding to the first RF signal responsive to the user channel selection. A second IF generator is operative to generate a second IF signal corresponding to the second RF signal responsive to the user channel selection. The first IF signal exhibits a predetermined frequency relationship relative to the second IF signal
