Electronics Digital circuits are electric circuits based on a number of discrete voltage levels. Digital circuits are the most common physical representation of Boolean algebra, and are the basis of all digital computers. To most engineers, the terms digital circuit, digital system and logic are interchangeable in the context of digital circuits. Most digital circuits use a binary system with two voltage levels labeled 0 and 1.

Construction eTool Circuit: The path along which electric current flows from start to finish is called a circuit. The circuit includes the generator or battery which starts the current, the wires, and any electrical device that the current operates. If any part of the circuit is removed, the current cannot flow. The circuit is then broken or open. Because electric current seeks to complete its circuit, it will travel along any path that is presented (path of least resistance), which is why humans are at risk of electrocution when they handle damaged tools or cords, or contact un-insulated wires.

PLD Related Terms. Short for programmable logic device, a generic term for an integrated circuit that can be programmed in a laboratory to perform complex functions. A PLD consists of arrays of AND and OR gates. A system designer implements a logic design with a device programmer that blows fuses on the PLD to control gate operation. System designers can use development software that converts basic code into instructions a device programmer needs to implement a design.

Charge-coupled device A charge-coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value. This is achieved by shifting the signals between stages within the device one at a time.

Electronic circuit Electronic circuit. An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow. To be referred to as electronic, rather than electrical, generally at least one active component must be present. The combination of components and wires allows various simple and complex operations to be performed: signals can be amplified, computations can be performed, and data

circuit 1) In electronics, a circuit is a path between two or more points along which an electrical current can be carried. (A circuit breaker is a device that interrupts the path when necessary to protect other devices attached to the circuit - for example, in case of a power surge.) 2) In telecommunications, a circuit is a discrete (specific) path between two or more points along which signals can be carried. Unless otherwise qualified, a circuit is a physical path, consisting of one or more wires (or wireless paths) and possibly intermediate switching points.

P wave (electrocardiography) The P wave is a summation wave generated by the depolarization front as it transits the atria. Normally the right atrium depolarizes slightly earlier than left atrium since the depolarization wave originates in the sinoatrial node, in the high right atrium and then travels to and through the left atrium.

PIN diode A PIN diode is a diode with a wide, undoped intrinsic semiconductor region between a p-type semiconductor and an n-type semiconductor region.The p-type and n-type regions are typically heavily doped because they are used for ohmic contacts.The wide intrinsic region is in contrast to an ordinary PN diode. PIN diode operates under what is known as high-level injection. In other words, the intrinsic i region is flooded with charge carriers from the p and n regions. Its function can be likened to filling up a water bucket with a hole on the side. Once the water reaches the hole's level it will begin to pour out.

Electric Circuits Electric Circuits. An electric circuit is a conducting path, external to the battery, which allows charge to flow from one terminal to the other. A simple circuit might consist of a single strand of metal wire linking the positive and negative terminals.uppose that a (positive) charge is driven around the external circuit, from the positive to the negative terminal, by the electric field set up between the terminals.

Partition coefficient In the physical sciences, a partition-coefficient (P) or distribution-coefficient (D) is the ratio of concentrations of a compound in a mixture of two immiscible phases at equilibrium. This ratio is therefore a measure of the difference in solubility of the compound in these two phases.

Semiconductor When a doped semiconductor contains mostly free holes it is called p-type, and when it contains mostly free electrons it is known as n-type. The semiconductor materials used in electronic devices are doped under precise conditions to control the concentration and regions of p-and n-type dopants.oped semiconductors are referred to as extrinsic. By adding impurity to the pure semiconductors, the electrical conductivity may be varied by factors of thousands or millions.

- A p–n junction. The circuit symbol is shown: the triangle corresponds to the p side. See also: p–n diode and Diode § Semiconductor diodes. A p–n junction is a boundary or interface between two types of semiconductor material, p-type and n-type, inside a single crystal of semiconductor.he electrons that cross the p–n junction into the p-type material (or holes that cross into the n-type material) will diffuse in the near-neutral region. Therefore, the amount of minority diffusion in the near-neutral zones determines the amount of current that may flow through the diode.

Lessons In Electric Circuits -- Volume I Electric circuits. 1  REVIEW: 2  A circuit is an unbroken loop of conductive material that allows electrons to flow through continuously without beginning or end. 3  If a circuit is broken, that means its conductive elements no longer form a complete path, and continuous electron flow cannot occur in it. The location of a break in a circuit is irrelevant to its inability to sustain continuous electron flow.
