METHOD FOR SEARCHING CHANNEL USING AUTOMATIC GAIN CONTROL VOLTAGE

摘要

PURPOSE: A method for searching channel using automatic gain control voltage is provided to check the automatic gain control voltage for controlling broadcasting signals having different levels into signals having uniform level, thereby more quickly and accurately searching channels. CONSTITUTION: A method for searching channel using AGC(automatic gain control) voltage comprises a step(100) memorizing the automatic gain control voltage corresponding to input sensitivity by frequency range, a step(200) checking the AGC voltage with varying receive frequency to every unit frequency, and a step(300) setting the receive frequency when the memorized automatic gain control voltage is generated as a channel frequency.
