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)

Phase shift keying is the form of Bluetoot

h modulation used to enable the higher data rates achievable with Bluetooth 2 EDR (Enhanced Data Rate). Two forms of PSK are used: Ï-/4 DQPSK, and 8DPSK.
