wavelessとは 意味・読み方・使い方

The receiver checks for carrier wave of an announcement broadcast signal, and when it detects carrier-waveless, it considers that a line error, such as a disconnection or the like, has occurred on the CATV community line L and switches to an internal antenna 5, as well as making local oscillating frequency variable, in order to receive general broadcast.例文帳に追加

告知放送信号の搬送波の有無を検出し、搬送波無しを検出した時には、ＣＡＴＶ共聴ラインＬに断線等の線路障害が発生したと見做して、内部アンテナ５に切替えると共に、一般放送を受信するために局部発振周波数を可変にする構成を備える。 - 特許庁
