Which type of modulation is most commonly used in analog communication systems?

Which type of modulation is most commonly used in analog communication systems?

Step 1: Understand what modulation means. Modulation is a technique used to encode information onto a carrier wave for transmission.
Step 2: Learn about different types of modulation. The main types are Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM).
Step 3: Identify where modulation is used. Modulation is commonly used in radio, television, and other forms of communication.
Step 4: Recognize that Amplitude Modulation (AM) is a specific type of modulation where the amplitude (strength) of the carrier wave is varied to represent the information.
Step 5: Note that AM is widely used for broadcasting radio signals, especially in analog communication systems.
Step 6: Conclude that the most commonly used type of modulation in analog communication systems is Amplitude Modulation (AM).
