The key difference between analog and digital signals lies in their nature and how they represent information.

Analog Signals

An analog signal is a continuous wave that can take on an infinite number of values within a given range.
Think of it like a dimmer switch for a light: you can adjust it to be any brightness between off and full-on. Analog signals are often used to represent natural phenomena, such as sound waves, temperature, or light. A classic example is a vinyl record player, which uses a continuous groove to reproduce the vibrations of the original sound.
The main characteristics of analog signals are:

Continuous: The signal can vary smoothly and continuously over time.

Infinite values: It can take on any value within a range.

Susceptible to noise: They are more prone to degradation and noise, which can distort the original information during transmission.

Digital Signals

A digital signal is a discrete wave that represents data as a sequence of distinct, separate values.
These signals are typically represented in binary code, using only two values: 0s and 1s.
This is similar to a light switch that is either on or off, with no in-between states.
Digital signals are the foundation of modern technology, including computers, smartphones, and CDs.
