Реферат: A monolithic integrated circuit includes a tuner (60) and a SAW filter (65) function. The tuner receives a radio frequency (RF) television signal that has a range of fundamental frequencies from 55 mega hertz (Mhz) to 880 Mhz. The tuner down converts the RF television signal to an intermediate frequency (IF) television signal that has a low fundamental frequency. In one embodiment, the SAWF (65) filter performs the SAW filter function on the IF television signal. In another embodiment, the SAWF filter performs the SAW filter function at baseband. An IF processor for processing the IF television signal to generate a video television signal and an audio television signal is disclosed.
