Two binary values are represented by two different frequencies in :
[A]
amplitude-shift-keying
[B]
frequency-shift-keying
[C]
phase-shift-keying
[D]
none of these above
Answer & Explanation
Option: [B]
Frequency shift keying is a digital signal transmission method in which the two binary states (logic 0 for low and logic 1 for high) are represented by carrier waves.
