IR LED (infrared light-emitting diode)

An IR LED is a special type of LED that emits infrared light. Infrared light is invisible to the human eye, but it can be detected by special sensors. IR LEDs are used in a variety of applications, including remote control devices, night vision cameras, and fiber optic communications. What is the difference between LED … Read more


In electronics, parallax refers to the apparent shift in position of an object when viewed from different angles. This phenomenon is caused by the different angles at which the object is viewed from different vantage points. The term is often used in relation to optical instruments such as telescopes and microscopes, where the apparent position … Read more

Soap opera effect (motion interpolation)

The soap opera effect is a phenomenon whereby a video image appears to be composed of a sequence of still images, giving it a ‘soap opera’ or ‘television-like’ appearance. This effect is caused by the use of a technique called motion interpolation, whereby new frames are generated between existing ones, in order to give the … Read more

Cosine wave

A cosine wave is an oscillating electrical signal with a waveform that is identical to the cosine function. Cosine waves are commonly used in electronic signal processing and telecommunications applications. What is cosine wave equation? A cosine wave is a waveform that oscillates between two values at a constant rate. The cosine wave equation is … Read more


An inductor is a device that stores energy in the form of a magnetic field. It is made up of a coil of wire that is wrapped around a core of material, usually iron. The inductor can be used to store energy in the form of a magnetic field, or to block the flow of … Read more

Low-light imaging

Low-light imaging is a type of photography that is used to capture images in low-light conditions, such as at night or in a dark room. This type of photography requires a camera with a high ISO setting and a fast shutter speed to avoid blur. What is low light camera performance? Low light camera performance … Read more

Electron rest mass

The electron rest mass is the mass of an electron when it is at rest. It is a fundamental property of the electron, and is one of the reasons why it is such an important particle in electronics. The electron rest mass is very small, but it is not zero. This means that even when … Read more


A harmonic is an electrical signal that is an integer multiple of the fundamental frequency. The fundamental frequency is the lowest frequency in a signal. The harmonics are the higher frequencies that are present in a signal. Harmonics are important because they can cause problems with the operation of electronic equipment. What is harmonic sound? … Read more


A solenoid is a coil of wire that creates a magnetic field when an electric current is passed through it. The term is also used to refer to a device that converts electrical energy into mechanical energy, such as a door lock or a linear actuator. What is a solenoid in simple terms? A solenoid … Read more

LED light bulb

An LED light bulb is a light bulb that uses light-emitting diodes (LEDs) as its source of light. LED light bulbs are more energy-efficient and have a longer lifespan than traditional incandescent light bulbs. What are the 3 types of LED light bulbs? There are three types of LED (light-emitting diode) bulbs: standard, candelabra, and … Read more
