e/On-off keying

Information
has gloss	eng: On-off keying (OOK) the simplest form of amplitude-shift keying (ASK) modulation that represents digital data as the presence or absence of a carrier wave. In its simplest form, the presence of a carrier for a specific duration represents a binary one, while its absence for the same duration represents a binary zero. Some more sophisticated schemes vary these durations to convey additional information. It is analogous to unipolar encoding line code.

Meaning
Italian
has gloss	ita: L'On-Off Keying (OOK) è un tipo di modulazione ASK che rappresenta i dati digitali come presenza o assenza di una portante. Nella sua forma più semplice, la presenza di una portante per un tempo specifico rappresenta un uno binario, mentre la sua assenza per la stessa durata temporale rappresenta uno zero. Alcuni schemi più complessi variano queste durate per convogliare informazione aggiuntiva.

has gloss	jpn: オンオフ変調もしくはオンオフキーイング(英：on-off-keying、略号：OOK)は、搬送波の有無によりデジタルデータを表す変調方式の一種であり、振幅偏移変調の最も単純な形式である。最も単純な形式として、ある時刻における搬送波の存在は、バイナリーで1を表し、ある時刻における搬送波の欠如(存在しない状態)は、バイナリーで0を表す。より複雑な手法として、追加情報を与えるため、オン、オフの長さを変化させる場合(例：モールス信号)もある。
