Analog Electronics

Analog electronics is a branch of electrical engineering and a kind of electronic system that deals with continuously variable signals. Analog messages are sent as signals of varying frequency. The proportional relationship exists between a signal and a voltage or current in an analog circuit.

Everything in the real world is analog and analog information surrounds us everywhere. Analog electronics are used to convert analog signals into digital ones that are easily proceed and stored, they also amplify, attenuate, isolate, modify, and even distort signals. These include various analog devices, mechanical and electronic, which convey analog information (sounds, visuals, etc.), radio and audio equipment. Analog electronic devices store information on physical mediums like tapes, films, etc.

Analog methods used in analog electronics allow the equipment to handle information that continuously changes like the voltage, current, and waves. Usually, they operate with time-varying quantities. Analog electronics help to measure, track and adjust numerous parameters including pressure, speed, atmospheric humidity, and many more.

Digital electronics is also widespread and highly used, but analog electronics are a necessity and play an important role in electronic development. Moreover, any time when digital electronics interact with the real world, analog electronics are indispensable to provide this interaction.

Analog electronics provides high accuracy and speed in applications when conversion to and from the digital format is necessary. Analog electronics also has low sensitivity to interference and EMC immunity and is applicable in cases of low power. It is a great advantage because electromagnetic fields and other factors can usually cause interference and affect the reliability and functionality of electronics.

There are two large groups of analog circuits: passive and active. Currently, completely analog circuits are a rarity and often include also digital or microprocessor techniques to improve performance. The combination of analog and digital technologies, microcontrollers, and other components often is used to ensure flexibility and develop a first-rate end product relevant to all safety requirements.

Analog circuits include simple and complex combinations of basic electronic components and realize various actions with signals. Smart choice of concept and components, and precisely created electronic circuit schematic provide development of high-quality products, keep down production costs and final cost of the product. Therefore precise schematics are created and then used to develop robust, reliable, safe, and efficient analog circuits and analog electronics.
