The ionization chamber is the simplest type of gaseous ionisation detector, and is widely used for the detection and measurement of many types of ionizing radiation, including X-rays, gamma rays, alpha particles and beta particles. Conventionally, the term "ionization chamber" refers exclusively to those detectors which collect all the charges ...
From a mathematical perspective, an eye pattern is a visualization of the probability density function (PDF) of the signal, modulo the unit interval (UI). In other words, it shows the probability of the signal being at each possible voltage across the duration of the UI. Typically a color ramp is applied to the PDF in order to make small ...
Digital micromirror device. A DMD chip, used in most projectors and some TVs. The digital micromirror device, or DMD, is the microoptoelectromechanical system (MOEMS) that is the core of the trademarked Digital Light Processing (DLP) projection technology from Texas Instruments (TI). Texas Instrument's DMD was created by solid-state physicist ...
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board. The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are grouped or matched with ...
An armed man with body armor, knives and suspicious writings that included the words "You gonna learn today" was arrested Wednesday in New York City.
Schematic diagram of an opto-isolator showing source of light (LED) on the left, dielectric barrier in the center, and sensor (phototransistor) on the right An opto-isolator (also called an optocoupler , photocoupler , or optical isolator ) is an electronic component that transfers electrical signals between two isolated circuits by using light ...
The internet is heated over this mother-of-the-bride dress. One mother of the bride is causing a stir online for her attire — and not because she wore white. “The most stunning MOB dress we ...
Attenuator. An attenuator is an electronic device that reduces the power of a signal without appreciably distorting its waveform . An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than 1.
