Questions & Step-by-Step Solutions
What is the primary advantage of using digital signals over analog signals in communication systems?
Correct Answer: Digital signals are less susceptible to noise.
Step 1: Understand what digital signals are. Digital signals represent data in binary form (0s and 1s).
Step 2: Understand what analog signals are. Analog signals represent data in a continuous wave form.
Step 3: Learn about noise. Noise refers to unwanted disturbances that can affect signals during transmission.
Step 4: Compare how digital and analog signals handle noise. Digital signals can be more easily distinguished from noise because they have clear, distinct values (0s and 1s).
Step 5: Conclude that because digital signals are less affected by noise, they are more reliable for communication than analog signals.
