MIX1 UNIT MAIN UNIT (AUDIO DEMODULATION) The received signals from the RF-B UNIT are mixed with 1st The 3rd/4th IF signal from the RF-A UNIT is applied to the A/ LO signals from the PLL UNIT, to generate 1st IF signal. The D converter (IC1305) via buffer, and converted into the digital generated 1st IF signal is applied to the RF-B UNIT again, audio signal.
-VIDEO AM-DEMODULATION- (except for USA version) The 2nd IF signal divide at the splitter is amplifi ed and fi ltered, then converted into the 3rd IF (video IF) signal at 3rd mixer (IC2201). The converted video IF signal is amplifi ed, then passed through the video IF fi lters. The fi ltered video IF signal is applied to the video demodulation IC and AM-demodulated.
