Question

Distinguish between analog and digital signals.

Answer 1

Both the signals convey information in its own way and have unique characteristics and everyday applications. The way in which signals are processes are the basis to distinguish between them.

Complete step-by-step solution
Signals are functions which carry information regarding electric and communications. It is used to indicate and represent the data at a given time which depends on various physical quantities. It is used to carry data from one device or a medium to another.
The signal is classified into two types: digital and analog. They both differ in their properties and have different characteristics.

Digital Signal	Analog Signal
These signals have non-continuous electrical signals.	These signals have continuous signals.
They are represented by square waves	They are represented by sine waves
The range of values are discontinuous	The ranges of values are continuous.
They can be converted into binary waves	They are recorded as sound waves.

These are the differences between digital and analog signals.
Note: Digital signals are used in processing speech, in radar, sensor programs, image processing, telecommunication, control systems, in microprocessors, in electronic products, data transmitting equipment and more whereas analog signals are used to convey information like electrical signals, current, voltage, frequency. They are used in telephones, tapes, old versions of televisions, photocopiers and more devices.
