Communication Systems employing electrical signals to convey information from one place to another over a pair of wires provided an early solution to the problem of fast and accurate means of long distance communication. Today communication enter in our daily lives in so many different ways that is easy to overlook the multitude of its facets. The Mobile phones at our hands, the radio and the television which are the basic and necessary part of our life are capable of providing rapid communication from every corner of globe. Analog and digital Communication are the major mode of communication.

FAQs
Q1: What is the difference between analog and digital communication?
A1: Analog signals are signals with continuous values. Digital signals are represented by binary numbers. 1 and 0. Analog signals are used in many systems. Although, the usage of analog signals has declined with the advent of several cheap digital signals.
Q2: What are the examples and applications of analog and digital communication?
A2:
| Analog | Digital | |
| Examples | Human voice in air, analog electronic devices. | Computers, CDs, DVDs, and other digital electronic devices. |
| Application | Thermometer | PCs, PDAs |
Q3: How do we graphically represent analog and digital communication process?
A3:
Q4: Which one is better – analog or digital?
A4:
| Analog System | Digital System |
| Inexpensively communicate a band limited analog signal from one location to another | Offer much more efficiency, better performance, and much greater flexibility |
| Point-to-point communication | Increasingly efficient algorithms |
| Receiver provides the largest possible signal-to-noise ratio for the demodulated message | Ability to interconnect computers to form a communications infrastructure |
| Some residual error will always be present in an analog system’s output | Almost nil residual error |
| Less expensive | Expensive |
