What type of modulation uses discrete values of carrier frequencies to transmit binary data?
A)
Phase modulation
B)
Frequency modulation
C)
Frequency shift keying
D)
Amplitude shift keying

Correct Answer :   Frequency shift keying


Explanation : Frequency shift keying assigns different values of carrier frequencies for binary digits and transmits data by varying the frequency of the carrier in accordance with the binary data. This type of modulation is widely used in the transmission of binary data in digital cell phones and in some types of low speed modems.
