WebThe most basic modulation method is called On–Off Keying (OOK). Just shut off the RF carrier if there is a zero to transmit, and send a full-power carrier if there is a one, and you have an OOK modulator. This is of course a form of amplitude modulation (AM), and it is used in many low-cost devices such as garage door openers. Web21 de fev. de 2024 · On-off keying (OOK) is a modulation scheme that consists of keying a sinusoidal carrier signal on and off with a unipolar binary signal. OOK is equivalent to …
