Web6.2 ON–OFF KEYING. In OOK encoding, the optical light is pulsed on or off during each bit time, as shown in Figure 6.2a. Each “1” bit is encoded into an optical pulse and each “0” bit is encoded into an off (no field) bit. Clearly, the maximum source bit rate is directly related to the rate at which the source can be switched on and off.

WebDigital amplitude modulation involves varying the amplitude of a carrier wave in discrete sections according to binary data. The most straightforward approach to digital amplitude modulation is on-off keying. With digital frequency modulation, the frequency of a carrier or a baseband signal is varied in discrete sections according to binary data. オンオフ変調（オンオフへんちょう、英語: on-off-keying、略号：OOK、オンオフキーイング）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 …
