A demodulator is a circuit that performs which process?
AAmplifying the carrier wave
BIncreasing the antenna length
CMultiplexing many channels together
DThe inverse of modulation
Answer & Solution
Correct answer: D. The inverse of modulation
Demodulation recovers the original message from the modulated carrier, reversing what the modulator did.
