Analog Electronic Circuits
Our world is analog in its nature because analog includes all real and continuous. The smells, sounds of nature, musical instruments or birds, tones, colors on the paintings, lighting, and temperature are analog signals. All these signals are received as analog by human sense organs, and further, the information is processed in the brain.
Analog electronics is a branch of electronics related to real and continuously variable analog signals. These devices transform the information into electric pulses of varying amplitude. Analog electronics include analog devices and circuits, radio and audio equipment, landline telephones, analog voltmeters, ammeters and wattmeters, thermostats, loudspeakers, audio amplifiers, ambulance sirens, telautographs, sensors. The devices, which take analog signals at the entrance and convert them into digital signals for further storage and processing also belong to analog electronics.
Analog signals use the properties of the medium to convey information. An analog signal is time-varying and takes values in a certain range. Each value corresponds to certain information and the change of signal leads to a change of value on analog equipment.
Analog electronic circuits show a combination of various electronic components like resistors, operational amplifiers, capacitors, diodes, transistors, inductors, and many other analog components and their interconnections. The simple analog circuits include a small number of devices, even only two resistors may be included. In turn, the complex schematics may include a large number of basic electronic components in various combinations. Usually, complex circuits are hard to design. High accuracy is necessary because complex analog circuits perform a lot of actions, they can attenuate, amplify, isolate, modify, distort the signals, and even convert them into digital signals.
Example 1. Analog Electronic Circuits
Analog components are durable and have great characteristics, but are susceptible to undesired variations in voltage, thermal vibrations, and random disturbances called noise. All variations and disturbances are significant for an analog signal because being transmitted over long distances these variations lead to signal degradation. Even insignificant changes in an analog signal can cause significant errors when being processed.
One differs two types of analog circuits: passive and active. The main difference is that passive analog circuits don’t consume any electrical power. The passive electronic components of analog circuits are resistors, inductors, capacitors, and memristors. Active components are diodes, transistors, and amplifiers.
