What does binary mean in the context of digital signals?
Back
Binary refers to a system that uses two distinct values, typically 0 and 1, to represent information.
5.
FLASHCARD QUESTION
Front
Why are digital signals less likely to be affected by noise than analog signals?
Back
Digital systems can easily filter out non-binary noise, making them more robust against interference.
6.
FLASHCARD QUESTION
Front
What happens to sound quality when analog signals are transmitted over long distances?
Back
Analog signals can degrade and lose quality due to interference and noise over long distances.
7.
FLASHCARD QUESTION
Front
What is the role of a radio receiver in an analog radio?
