What is Analog Communication 

Analog Communication is the transfer or transmission of information sent via electric pulses with alternating amplitude.

In communication technology, the 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. 


Components of Analog Communication

1. The sender: This is the initiator of the message, this person sends a message, through a transmitting station from where the signal is transmitted.

2. Channel: is the medium through which the message signals travel to reach the destination.

3. The receiver: is the person who receives the message through a receiving station where the transmitted signal is being received.


Types Of Signals include:

1. Analog Signal: An analog signal is any continuous signal for which the time-varying feature (variable) of the signal is a representation of some other time-varying quantity, i.e., analogous to another time-varying signal. The signal actually is electronic signals specifically (as opposed to traffic signals, albums by the ultimate power-trio, or a general means for communication). The signals we're talking about are time-varying "quantities" which convey some sort of information. In electrical engineering, the quantity that's time-varying is usually voltage (if not that, then usually current). So just think of them as a voltage that's changing over time. Signals are passed between devices in order to send and receive information, which might be video, audio, or some sort of encoded data. Usually, the signals are transmitted through wires, but they could also pass through the air via radio frequency (RF) waves. Audio signals, for example, might be transferred between your computer's audio card and speakers, while data signals might be passed through the air between a tablet and a WiFi router.

2. Digital Signal: Digital signals must have a finite set of possible values. The number of values in the set can be anywhere between two and large-number, not infinity. Most commonly digital signals will be one of two values -- like either 0V or 5V. Timing graphs of these signals look like square waves, Or a digital signal might be a discrete representation of an analog waveform.


Features and Benefits of Analog Communication

1. In Analog Transmission, information is sent via electric pulses with alternating amplitude. Whereas in digital transmission, information to be sent is 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 have to be a media of transmission – a path through which the communication signals must follow. It could be via water, electrical cables, air or fiber. While each of these communication media can transmit a large amount of data, fiber 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 a 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.
