What is the difference between analogue and digital signal?

Evaluate responses using AI:

OFF

Answer explanation

Analogue signals are continuous and can take any value within a range, representing information in a wave-like form. Digital signals, on the other hand, are discrete and represent information in binary form (0s and 1s).

Why do we need to use digital representation to describe analogue system?

Evaluate responses using AI:

OFF

Answer explanation

Digital representation is essential for accurately processing, storing, and transmitting analogue signals. It allows for easier manipulation, error correction, and integration with digital systems, enhancing efficiency and reliability.

List the advantages and disadvantages of digital system over analogue system.
