A TRIAC is used in AC power control applications in order to switch high voltages over both parts of the AC waveform. As a result, TRIAC circuits are used in a number of applications that require power switching. The TRIAC was developed after the thyristor, which controls AC current over one half of the cycle. …
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 …
A Trivial File Transfer Protocol (TFTP) server is based on a simple Fire Transfer Protocol (FTP) that was first defined in 1980. TFTP books routers and other computers that do not have storage devices. It also transfers small files between two or more computer network hosts such as a transfer initiated on a remote X …
The Toshiba Corporation was originally founded in 1939 through the merger of Tanaka Engineering Works and Hakunetsusha (later renamed to Tokyo Electric). Over the course of the 20th and 21st Centuries, the corporation has seen significant expansion into a number of technical fields to include being one of the top five producers of consumer laptops …
Humidity sensors (hygrometers) measure and report the air’s relative humidity. They are used in homes, wine cellars, and working environments that that are so humid that they negatively impact working conditions. Humidity sensors are also used in vehicles, industrial HVAC systems, and meteorological stations to help in the predicting and reporting of weather conditions. How …
A multivibrator is an electronic circuit that rapidly switches because of positive feedback between multiple states. The switch’s output is harmonic. Three types of multivibrator circuits are used in industry today: astable, monostable, and bistaple. Types of Multivibrators The three multivibrator types are: Astable Multivibrator – The circuit is not considered stable in either of …
The Hot Standby Router Prtocol (HSRP) is a networking protocol that supports the non-disruptive failover of Internet Protocol (IP) traffic in special circumstances. HSRP also allows network hosts to look like they are using a single router and keep connected if the first hop router being used fails to respond. The protocol guards against the …
CPUs process data using instructions stored in the computer memory or RAM. The RAM is a temporary storage area that makes information and instructions available to the microprocessor, which does not have to use this information until required. The two processor classifications are the Reduced Instruction Set Computer (RISC) and the Complex Instruction Set Computer …
A petabyte is a measurement unit that describes a piece of information that is equal to 1,000 terabytes or one quadrillion bytes of data. A single petabyte is equal to 1,000,000,000,000,000 bytes . When a petabyte describes computer memory, it is also used in reference to a corresponding power of 1024. The approved scientific symbol …
A Karnaugh map is a graphical method or shortcut that can be used to solve Boolean algebra problems. Boolean algebra is used to conduct computations and create expressions from two values. This type of math creates the basis behind much of computer science and modern circuit card design today. Maurice Karnaugh created the current version …
