ABSTRACT:
A television tuner (920) is adapted for use in a television receiver (900) that receives a radio frequency (RF) signal from an input device (910) and outputs audio and video information from a selected channel in response thereto. The television tuner (920) includes a direct digital frequency synthesizer (206) and a mixer (220). The direct digital frequency synthesizer (206) has an output for providing a digital representation of a mixing signal. The mixer (220) has a signal input for receiving a television signal, a mixing input coupled to the output of said direct digital frequency synthesizer (206), and an output for providing an intermediate frequency (IF) television signal.
