Analogue And Digital

Question 1

What does the term ‘Analog’ refer to?

Answer 1

Analog refers to a continuous signal

It has a smooth and flowing nature.

Question 2

How do analog signals operate?

Answer 2

Analog signals operate like a wave that can take any value in a range.

Example: A dimmer switch that gradually brightens or dims a light.

Question 3

What is the range of values for analog signals?

Answer 3

Values change continuously, not in steps.

Typically within a range of 0 to 1023.

Question 4

Can you name examples of analog signals?

Answer 4

Examples of analog signals include:
* Sound waves
* Light intensity
* Temperature

Additional examples include analog clocks and old radios.

Question 5

What does ‘Digital’ refer to?

Answer 5

Digital refers to a signal that represents data as a sequence of discrete values, usually as 0s and 1s (binary code).

This allows for precise representation of data.

Question 6

How do digital signals operate?

Answer 6

Digital signals jump from one value to another in steps.

Example: A light switch that is either on or off—no in-between.

Question 7

What are the characteristics of digital signals?

Answer 7

Characteristics of digital signals include:
* Values change in clear steps, not continuously
* More exact and easier for computers to process
* Can be stored, copied, and transmitted without losing quality

This makes digital signals preferable for many applications.

Question 8

Can you name examples of digital signals?

Answer 8

Examples of digital signals include:
* Digital Clock
* Smartphone

These devices utilize digital signals for accurate timekeeping and communication.

Question 9

True or False: Analog systems are still used where smooth, natural changes are needed.

Answer 9

True

Analog systems are preferred in certain musical instruments and old radios.
