In computing, an arithmetic logic unit (ALU) is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. [ 1 ] [ 2 ] This is in contrast to a floating-point unit (FPU), which operates on floating point numbers.
Various electronic components, with a 15 cm ruler to scale. An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields.
In photography, secondary, or slave, flash units are connected to a master unit to provide synchronized lighting. Parallel audio duplication often entails multiple recording devices (i.e. for cassette tape or compact disc) linked together so that operating the controls of a master device triggers the same commands on slave devices.
SNCF Class B 81500, an example of an electro-diesel multiple unit. An electro-diesel multiple unit (EDMU) or bi-mode multiple unit (BMU) is a form of a multiple unit train that can be powered either by electric power picked up from the overhead lines or third rail (like an electric multiple unit – EMU) or by using an onboard diesel engine, driving an electric generator, which produces ...
Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
An HVDC thyristor valve tower 16.8 m tall in a hall at Baltic Cable AB in Sweden A battery charger is an example of a piece of power electronics. Power grid designer in front of a newly installed 880kV thyristor valve array A PCs power supply is an example of a piece of power electronics, whether inside or outside of the cabinet.
Symmetry (left) and asymmetry (right) A spherical symmetry group with octahedral symmetry.The yellow region shows the fundamental domain. A fractal-like shape that has reflectional symmetry, rotational symmetry and self-similarity, three forms of symmetry.
Electronic light sensors. Optoelectronics (or optronics) is the study and application of electronic devices and systems that find, detect and control light, usually considered a sub-field of photonics.
