Question
A modulated signal is formed by ________.a.Quantization of the source datab.Sampling at the Nyquist frequencyc.Changing the carrier wave by the modulating signald.Changing the modulating signal by the carrier wave
Solution
The correct answer is c. Changing the carrier wave by the modulating signal.
Here's a step by step explanation:
-
Modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a modulating signal that typically contains information to be transmitted.
-
The carrier wave is a specific kind of wave on which information can be imposed. It's usually a high frequency electromagnetic wave that can be modulated, either in amplitude, frequency or
