MODULATION AND DEMODULATION D ata modulators, especially those intended to produce constant- and frequency shift keying (FSK). Simulation Issues Block diagram of QPSK modulator. to the carrier frequency, the modulated signal is given simply as. x(t) ˜ = I(t) +. FSK: Signals and Demodulation Frequency shift keying (FSK) is the most common form of digital modula tion in the high -frequency radio spec trum, and has important applications in telephone circuits. This article pro vides a general tutorial on FSK in its many forms. Both modulation and demodulation schemes will be dis cussed Binary FSK. Implementation of FSK Modulation and Demodulation using CD74HCA technique known as frequency-shift keying (FSK). FSK is widely used in modems, radio-teletype and fax modems, and can also be used to send Morse code. 2 Basic Block Diagram of a PLL as a Modulator.

Fsk modulator and demodulator block diagram algebra

Frequency Shift Keying (FSK) is the digital modulation technique in which the frequency of the carrier signal varies according to the digital signal changes. FSK is a scheme of frequency modulation. The output of a FSK modulated wave is high in frequency for a binary High input and is low in frequency for a binary Low input.
