Question:What is meant by an Analogue Signal ?

An analogue signal is a signal thats value can vary continuously across a range of values.

In analogue communications, the information is the value of the size, or amplitude, of the signal at each point.

What this value (the number) actually means depends on what is being sent.

Note: Good exam answer: An Analogue signal is a signal thats value is continuously variable within a range.
