What is FSK Modulation and Demodulation Overview about?

FSK is a modulation technique where digital data is transmitted by discretely changing the frequency of a carrier wave. In binary FSK (BFSK), a pair of discrete frequencies represent binary 1s and 0s. FSK can be generated using an IC555 timer circuit where the output frequency depends on the digital input. FSK plays a key role in wireless data transmission and the circuit produces an FSK signal based on the input signal. An FSK demodulator uses a PLL and filter to detect the mark and space frequencies and r
