On–off keying (OOK) denotes 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 conve… Web2値の場合はOOK (on-off-keying) と呼ばれる。モールス符号を用いた電信はOOKの一種ともいえる。以前は、使用されることのほとんど無い変調方式であったが、 ETC やキーレスエントリー、 RFID タグなどの狭域通信（極めて近距離の通信）を中心に用いられることが多くなってきている。 WebVLC uses On-Off Keying (OOK) and Pulse Position Modulation (PPM).
