Abstract

이 발명은 수신장치에 관한 것으로서, 송신주파수와 수신주파수의 대역폭 차이를 측정하여 대역폭 차이에 해당하는 수신 주파수를 먼저 변환시켜 튜닝하게 함으로서 튜닝 시간을 단축하게 한 것임.The present invention relates to a receiving apparatus, by measuring a bandwidth difference between a transmission frequency and a reception frequency and converting a reception frequency corresponding to the bandwidth difference first to reduce the tuning time.
