Page 8: Working Principle Analysis Of The Unit
Working principle analysis of the unit The RF signal received by antenna will be sent to tuner TUN601, then IF signal will be obtained through high amplified and mixed frequency. After pre-intermediate amplified by V608, it will be sent to acoustic surface-wave Z605 to do IF filter and get better IF characteristics, then it will be sent to N602 (TDA4470) to do intermediate amplification, phase-lock loop VCO and synchronous wave detection to get the video signal TV-V;... -
