A circuit simulator is a computer program that predicts how electronic circuits work. Circuit designs are first entered through the schematic editor, then the simulation engine solves the complex equations that govern circuit behavior. Circuit simulators are especially useful for designing integrated circuits that are impractical to prototype using breadboards. The three types of simulator …
BGA (Ball Grid Array) is one type of packaging for surface-mounted integrated electronic circuits (integrated circuits whose components are actually ‘mounted’ or affixed on the surface of the printed circuit semiconductor board). A BGA package simply looks like a thin wafer of semi-conducting material that has circuit components on only one face. The Ball Grid …
A decoupling capacitor (bypass capacitor) is a device that separates current and voltage levels from two separate sections of the same electronic device. Decoupling capacitors are useful in situations that require an electronic device to fluctuate current or voltage levels without straining the power supply. Decoupling capacitors can be used in electronic devices that have …
VSWR (Voltage Standing Wave Ratio) is a metric commonly used with antenna systems for ham or shortwave radio communication. VSWR is normally defined as a ratio with a 1:1 VSWR, indicating that there is an exact or perfect match between all antenna system elements. The VSWR can also be expressed by comparing Vmax with Vmin …
Pulse position modulation is a signal modulation technique that allows computers to share data by measuring the time each data packet takes to reach the computer. It is often used in optical communication, such as fiber optics, in which there is little multi-pathway interference. Pulse position modulation exclusively transfers digital signals and cannot be used …
Satellite radio refers to a number of subscription-based radio broadcasting programs that are available in the US, Europe, and elsewhere that are dependent on satellites to provide mobile users with constant radio access. While terrestrial-based FM radio stations only provide radio broadcasts to a specific area, usually confined to the city they are located in, …
In a very simple sense, a capacitor is a device that stores energy in an electric field between two charged "plates" for a short period of time. The electric charge is then used or dissipated at an appropriate time. The capacitor essentially works along the same lines as the battery you might find in a …
MIL-C-5015, now known popularly as MS connectors, are multi-pin, highly durable connectors that were originally invented for use in military applications. They have a variety of features that makes them easy to use for nearly any application and are often found in a variety of advanced, high power, heavy duty devices in the industrial world. …
An EMF meter detects and measures an electromagnetic field. There are many types of EMF meters and they have many uses, including ghost hunting. Most EMF meters are “AC EMF meters” and can only detect the rate of change in an oscillating magnetic field. However, commercial grade EMF meters that can detect specific electromagnetic frequency …
A thyristor is a solid state semiconductor device that consists of four alternating layers of N-type and P-type material. Many sources consider thyristors to be the same as Silicon Controlled Rectifiers (SCRs). In some cases they are defined as a large group of devices – the eligibility criterion being that the device should consist of …
