Questions & Step-by-Step Solutions
Which type of modulation is most commonly used in digital communication systems?
Step 1: Understand what modulation means. Modulation is a technique used to encode information onto a carrier signal for transmission.
Step 2: Learn about different types of modulation. There are several types, including Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Shift Keying (PSK).
Step 3: Identify the purpose of digital communication systems. These systems transmit digital data over various channels.
Step 4: Recognize the importance of robustness in modulation. A good modulation technique should work well even in noisy environments.
Step 5: Discover that Phase Shift Keying (PSK) is commonly used because it is effective at resisting noise and maintaining data integrity.
Step 6: Conclude that PSK is the most commonly used type of modulation in digital communication systems.
