Frequency Shift Keying (FSK)

  • Saleh FaruqueEmail author
Part of the SpringerBriefs in Electrical and Computer Engineering book series (BRIEFSELECTRIC)


In frequency shift keying (FSK), the frequency of the carrier changes in discrete levels in accordance with the input digital signal, while the amplitude of the carrier remains the same. In this chapter, the FSK modulation will be presented along with the respective spectrum and bandwidth. These materials have been augmented by diagrams and associated waveforms to make them easier for readers to grasp.
