Test Your Knowledge on Amplitude Shift Keying (ASK) Technique

Amplitude Shift Keying (ASK)

• To study Amplitude Shift Keying, the required equipment includes a signal generator, an oscilloscope, and a pulse generator.

Modulation Technique

• The simplest method of modulating a carrier with a data stream in Amplitude Shift Keying is by varying the amplitude of the carrier wave in accordance with the data signal.

Alternative Name

• Amplitude Shift Keying is also known as On-Off Keying (OOK).

Modulation of Carrier Wave

• In Amplitude Shift Keying, the carrier wave is modulated by varying its amplitude in accordance with the data signal.

ASK Waveform Representation

• The ASK waveform represents the binary data being transmitted.

Modulation Technique

• Amplitude Shift Keying is a type of amplitude modulation technique.

Simplest Way of Achieving ASK

• The simplest way of achieving amplitude shift keying is by switching the carrier on and off in accordance with the binary data.

Generating ASK Waveform

• The ASK waveform can be generated using an oscillator, a switch, and a pulse generator.

Carrier Wave Modulation

• When the data bit is '1', the carrier wave is present, and when the data bit is '0', the carrier wave is absent.
