1.	Bluetooth uses ________(a) CDMA(b) Frequency hopping(c) QPSK(d) QAMThe question was asked during an internship interview.Query is from Reduction of Noise in section Modulation of Analog Communications
Answer» The correct choice is (b) Frequency hopping For EXPLANATION I would say: Bluetooth is a wireless TECHNOLOGY. It is USED for exchanging data over short distances. It USUALLY uses frequency hopping, in which the transmitter changes the carrier frequency with respect to a specific pattern.
