Analog Vs Digital Communication
As we see nowadays that more modern electrical devices are became digital by definition as opposed to analog
Parameter |
Analog |
Digital |
---|---|---|
Definition |
The analog devices or systems process analog signal which varies with time and have a continuous range of values also known as dynamic range |
The digital devices or systems process digital signals which have either one or zero values. |
Maintenance |
Troubleshooting and maintenance of analog signals and devices are difficult |
Troubleshooting of digital signals are easy and maintenance of digital devices is easy |
Noise immunity |
more vulnerable to noise |
stable and less vulnerable to noise |
Accuracy |
Not much accurate due to noise |
more accurate as it is more immune to noise |
Example |
For eg: Temperature, pressure etc |
Eg: Motor start, feedback(high or low), etc |
Synchronization problem |
Hard synchronization issues. |
Synchronization problem is much easier as compared to analog. |
Costing |
The cost of Analog communication system is low. |
The cost of Digital communication system is high . |
Portability |
less portable. |
High portability. |
Bandwidth requirement |
Low bandwidth is required. |
High bandwidth is required. |
Power consumption |
High power consumption. |
Low power consumption. |
Introduction to Analog Communication
Communication is the process of establishing a connection or link between two or more points for the exchange of information. Analog communication had a significant need for centuries as it has been a fundamental need of human interaction, which allows anyone with the continuous transfer of signals along with information. Let’s explore the basic principles, essential terminologies, applications, advantages, and limitations of analog communications in this article.
Whoever wants to understand how these communications systems work then it is required to first understand the fundamentals of analog communications. As we have seen a vast development of digital communications, still analog communications are very beneficial in almost every sector as everything around us is in analog form, including television, radio, broadcasting equipment, and telecommunications.
