What is the most commonly used demodulation technique for FSK?
The most used demodulation technique is the one using a PLL circuit (fig. 2). The FSK signal across the PLL input takes two frequency values. The error voltage supplied by the phase comparator follows such variations, and so, it constitutes the NRZ binary representation (high and low level) of the FSK input signal.
What are the different techniques to demodulate the FSK signal explain the techniques?
There are different methods for demodulating a FSK wave. The main methods of FSK detection are asynchronous detector and synchronous detector. The synchronous detector is a coherent one, while asynchronous detector is a non-coherent one.
What is FSK modulation and demodulation?
Frequency-shift keying (FSK) is the frequency modulation system in which digital information is transmitted through the discrete frequency change of a carrier wave. The technology is used in communication systems such as amateur radio, caller ID, and urgent situation broadcasts. The simplest FSK is binary FSK (BFSK).
