- Main differences between analog and digital communications
- Analog Communications
Until recently, most telephone, radio and television signals were sent via analog communication devices and is still used in circumstances where information is sent just a short distance due to the inexpensive nature of analog. In situations where analog was primarily the method of transmitting data, digital is now taking over. This is because analog is often open to interference and the communication is not always as clear as it should be. Many countries have now stopped using analog TV completely as the picture and sound quality is far superior on digital TV.
