Questions & Step-by-Step Solutions
Which modulation technique varies the amplitude of the carrier signal?
Step 1: Understand what a carrier signal is. A carrier signal is a wave that is used to carry information.
Step 2: Learn about modulation. Modulation is the process of varying a carrier signal to transmit information.
Step 3: Identify the types of modulation. There are different types of modulation techniques, such as Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM).
Step 4: Focus on Amplitude Modulation (AM). In AM, the amplitude (height) of the carrier signal is changed to represent the information being sent.
Step 5: Conclude that Amplitude Modulation (AM) is the technique that varies the amplitude of the carrier signal.
