Electronic devices on discrete components for industrial and power engineering.9781420069822 Electronic devices on discrete components An elementary electronic device constructed as a single unit. Before integrated circuits (chips), all transistors, resistors and diodes were discrete. They are widely used in amplifiers and other devices that use large amounts of current. for industrial and power engineering. Gurevich, Vladimir. CRC (Cyclical Redundancy Checking) An error checking technique used to ensure the accuracy of transmitting digital data. The transmitted messages are divided into predetermined lengths which, used as dividends, are divided by a fixed divisor. / Taylor & Francis 2008 419 pages $139.95 Hardcover TK7881 Gurevich, an electrical engineer now working with an electric company in Haifa, describes different functional units and automation devices for industry and electric power engineering that are implemented by modern discrete electronic elements without using micro-electronics or micro-processor-based technologies. They are much cheaper and easier to use than the fancy ones, he says, and can be produced by small companies and even independent amateurs. Among the devices are high-voltage reed relays As a relay is a switch controlled by an electromagnet, so a reed relay is one or more reed switches controlled by an electromagnet. The contacts are of magnetic material; thus the electromagnet acts directly on them rather than requiring an armature to move them. responding to the current changing rate, overcurrent and overvoltage protection modules, and high-current pulse transducer transducer, device that accepts an input of energy in one form and produces an output of energy in some other form, with a known, fixed relationship between the input and output. for metal-oxide surge arresters Surge arrester A protective device designed primarily for connection between a conductor of an electrical system and ground to limit the magnitude of transient overvoltages on equipment. A lightning arrester is really a voltage-surge arrester. . For each he provides a diagram and specifications. ([c]20082005 Book News, Inc., Portland, OR) |
