What is ASK Modulation?
Amplitude Shift Keying is a modulation technique used in communication systems.
In this technique, the amplitude of a carrier signal carrying digital data bits is changed relative to the data bits. That is, the amplitude of the carrier signal changes depending on whether the digital data is 1 or 0.
In ASK, two different amplitude levels are generally used: one representing the "1" state and the other representing the "0" state. Data bits are transmitted by varying the amplitude of the carrier signal. For example, a signal with a higher amplitude may represent "1" and a signal with a lower amplitude may represent "0".
The advantages of ASK include simple implementation, low cost, and good detection based on high amplitude variations. However, it is more noise sensitive than other modulation techniques and is preferred at lower data rates.
Generally, ASK can be used in fields such as wireless communication, radio transmission and optical communication.
We have done an application that works with the ASK modulation technique before. You can click the link below for the 433 MHz receiver and transmitter module application.
