Dynamic range

Dynamic range is a measure of the ability of an electronic system to reproduce the full range of frequencies that are present in the input signal. The dynamic range of a system is usually expressed in terms of the ratio of the largest to the smallest signal that can be reproduced without distortion. The dynamic … Read more

Abcoulomb (abC)

An abcoulomb (abC) is a unit of electric charge. It is defined as 10^-9 coulombs. What is the value of 1 emu? There is no definitive answer to this question as the value of 1 emu can vary depending on the specific context in which it is being used. However, in general, 1 emu is … Read more

Permeability (magnetic permeability)

Magnetic permeability is a measure of how easily a material can be magnetized. The higher the permeability of a material, the more easily it can be magnetized. The SI unit for magnetic permeability is the henry per meter (H/m). What is magnetic permeability formula? The magnetic permeability formula is: $$ mu = frac{B}{H} $$ where: … Read more

Linear integrated circuit (linear IC)

A linear integrated circuit (linear IC) is a type of integrated circuit (IC) in which the output signal is proportional to the input signal. Linear ICs are used to create amplifiers, filters, voltage regulators, and other types of circuits. The term “linear” refers to the fact that the output signal is a linear function of … Read more


A conductor is a material that easily allows electricity to flow through it. Metals are the most common type of conductor, but other materials can also be used, such as carbon or semiconductors. Conductors are used in electrical circuits to connect different components together. They can be used to create wires, cables, and other types … Read more


Torque is a force that tends to produce rotation. The concept comes from Newton’s second law of motion, which states that force is equal to mass times acceleration. In this context, force is the rotational equivalent of linear force, and mass is the rotational equivalent of linear mass. Just as a force is required to … Read more

Pink noise

Pink noise is a signal that has been generated by combining multiple noise sources together. The resulting signal has a flat power spectral density, which means that it has equal power at all frequencies. Pink noise is often used in audio applications, as it can help to mask other sounds that may be present. It … Read more

Compressed air

Compressed air is a type of air that has been compressed using a compressor. This results in a higher concentration of oxygen and other gases in the air, which can be used to power electronic devices. What is compressed air example? Compressed air is often used in electronic equipment, such as computers, to cool down … Read more


Photoconductivity is the increased electrical conductivity of a material in response to light. The effect is created by the absorption of photons, which creates free electrons and holes in the material. The free carriers increase the material’s conductivity. What is the photoconductive effect? The photoconductive effect is the increase in conductivity of a material when … Read more

Electronic nose (e-nose)

An electronic nose is a device that is used to identify and distinguish between different smells. It works by using sensors to detect the chemicals that are present in a sample, and then uses pattern recognition to identify the smell. Electronic noses are used in a variety of applications, such as food quality control, detection … Read more
