Bluetooth uses which digital modulation technique to exchange information between paired devices?

  • A. PSK (phase-shift keying)
  • B. FSK (frequency-shift keying)
  • C. ASK (amplitude-shift keying)
  • D. QAM (quadrature amplitude modulation)
Show Suggested Answer Hide Answer
Suggested Answer: A 🗳️
Phase shift keying is the form of Bluetooth modulation used to enable the higher data rates achievable with Bluetooth 2 EDR (Enhanced Data Rate). Two forms of
PSK are used: /4 DQPSK, and 8DPSK.

Selected Answer: B
B - Reason: The question asked about the modulation technique used by Bluetooth to exchange information between paired devices in general, not specifically for EDR. For standard Bluetooth (Basic Rate), the modulation technique used is Gaussian Frequency Shift Keying (GFSK)
