____ defines how data is placed on a carrier signal.
A)Modulation
B)Multiplexing
C)Digitization
D)Adaptation

Question

Quizplus · Accepted Answer

Modulation is the process of imposing information from a message signal onto a carrier signal by adjusting one or more characteristics of the carrier signal. These characteristics can be amplitude, frequency, or phase. Therefore, modulation defines how data is placed onto a carrier signal, making option A the correct choice.

B) Multiplexing involves combining multiple signals into a single signal to share a medium, but it does not specifically address how data is placed on the carrier signal.

C) Digitization is the process of converting analog signals into digital signals. While important in the transmission of data, it does not specifically address how data is placed on the carrier signal.

D) Adaptation is too general and does not specifically address how data is placed on the carrier signal.
