local down-burstとは 意味・読み方・使い方

In a control circuit 200, when a reception detecting circuit 70 detects reception of a burst signal, frequency of a local signal used for down conversion is changed by every 400 Hz by controlling a PLL circuit 30 every time when 128 symbols in a carrier regeneration code CR are received, and the above process is performed as far as a carrier regeneration detecting circuit 120 detects regeneration of a carrier.例文帳に追加

制御回路２００は、受信検出回路７０がバースト信号の受信を検出すると、搬送波再生符号ＣＲを１２８シンボルを受信する毎に、ＰＬＬ回路３０を制御して、ダウンコンバートに用いるローカル信号の周波数を４００Ｈｚづつ可変させ、この制御を搬送波再生検出回路１２０が搬送波再生を検出するまで行う。 - 特許庁
