Advantages and disadvantages of ASK

A digital modulation technique in which the amplitude of the carrier wave is altered according to the modulating signal is known as amplitude shift keying. It is the simplest and most straightforward method of digital modulation. So here this article gives the advantages and disadvantages of ASK to better understand this topic.

Advantages of ASK modulation:

  • It offers high bandwidth efficiency.
  • It has a simple receiver design.
  • Its generation and detection are easy thus facilitate a simple transmitter and receiver section.
  • ASK modulation and demodulation are relatively low-cost methods.
  • Its version OOK is used to relay morse codes over radio frequencies.
  • Digital data can be transmitted over optical fiber using ASK modulation.

Disadvantages of ASK modulation:

  • It offers lower power efficiency.
  • ASK modulation is very susceptible to noise interference. This is because noise has an impact on the amplitude.
  • Poor bandwidth efficiency.
  • ASK techniques are not suitable for high bit rate data transmission.
