Analog Communication is the transfer or transmission of information sent via electric pulses with alternating amplitude.
In communication technology, transmission is of two kinds: digital and Analog transmission. While both transmission systems are somewhat similar in that communication signals are sent electrically, they vary greatly.
1. In Analog Transmission, information is sent via electric pulses with alternating amplitude. Whereas in digital transmission, information to be sent are first converted to binary code – one and zero – before being transmitted in bits. High amplitude is represented by 1 while the low amplitude is represented by zero. Analog and digital transmission are inter-convertible – one can be converted to the other. Conversion is achieved through the use of a device called the Modem.
2. For Analog communication to work, there has to be a media of transmission – a path through which the communication signals must follow. It could be via water, electrical cables, air or fibre. While each of these communication medium can transmit a large amount of data, fibre transmits the most.
3. There are two major techniques for transmitting Analog communication signals:
a. Amplitude Modulation – or AM for short – and
b. Frequency Modulation, which we all know as FM.
The major difference between these transmission techniques is the distance they cover. AM signals can be transmitted to longer distance than FM.
4. Analog communication is way cheaper than digital communication. The reason is that unlike digital communication which requires lots of multiplexing which costs money, Analog communication does not.
5. Analog transmission is relatively immune to impedance problems.
