Amplitude Shift Keying
1. Where is ASK used?
ASK is commonly used in applications like RFID systems, remote controls, and some low-cost wireless communication systems.
2. How does ASK work?
ASK works by changing the amplitude of the carrier wave to encode binary data. It uses different amplitudes to represent different symbols or bits.
6. How is ASK demodulated?
ASK can be demodulated using techniques such as envelope detection or coherent detection. Envelope detection involves rectification, low-pass filtering, and threshold detection to extract the digital data.
Amplitude Shift Keying
In digital communication, different modulation techniques are used to transmit data or message to receiver over a communication channel . One such technique is Amplitude Shift Keying (ASK). It is a modulation technique that alters the amplitude of a carrier signal to transmit the information over channel. It is a modulation scheme having wide range of application in real world which includes radio, television, and digital data transmission.
