Claims (2)
튜너의 AGC출력을 PWM변조시키는 과정과, 상기 PWM변조 출력을 카운트하여 펄스폭이 넓은 PWM펄스를 선택하는 PWM펄스 선택 과정과, 상기 PWM펄스 선택 출력을 PLL데이타로 변화시킨 후 튜닝 IC에 인가시켜 주어 정튜닝을 행하는 과정을 수행하는 것을 특징으로 하는 AGC출력을 이용한 AFT방법.PWM modulation of the tuner's AGC output, PWM pulse selection process for counting the PWM modulation output to select a wide pulse pulse, and the PWM pulse selection output is changed to PLL data and then applied to the tuning IC. AFT method using the AGC output, characterized in that performing a process of performing the subject tuning.제1항에 있엇, PWM펄스 선택 과정은 PWM펄스의 하이레벨 구간을 카운트한 후 이를 비교하여 더 많은 카운트 값을 갖는 PWM펄스를 선택하도록 하는 AGC출력을 이용한 AFT방법.The method of claim 1, wherein the PWM pulse selection process counts the high-level section of the PWM pulses and compares them to select the PWM pulses with more count values.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
