  2. Fault detection and isolation - Wikipedia

    en.wikipedia.org/wiki/Fault_detection_and_isolation

    Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location.

  3. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

  4. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    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 ...

  5. Functional block diagram - Wikipedia

    en.wikipedia.org/wiki/Functional_block_diagram

    The functional block diagram can picture: [1] functions of a system pictured by blocks; input and output elements of a block pictured with lines; the relationships between the functions, and; the functional sequences and paths for matter and or signals [2] The block diagram can use additional schematic symbols to show particular properties.

  6. N2 chart - Wikipedia

    en.wikipedia.org/wiki/N2_Chart

    The N 2 chart or N 2 diagram (pronounced "en-two" or "en-squared") is a chart or diagram in the shape of a matrix, representing functional or physical interfaces between system elements. It is used to systematically identify, define, tabulate, design, and analyze functional and physical interfaces.

  7. Polarity symbols - Wikipedia

    en.wikipedia.org/wiki/Polarity_symbols

    Diagram showing positive tip polarity on the left and negative tip polarity on the right. To read diagram: The center positive drawing on the left indicates that the center (also known as the tip) of the output plug is positive (+) and the barrel (ring) of the output plug is negative (−).

  8. Penrose graphical notation - Wikipedia

    en.wikipedia.org/wiki/Penrose_graphical_notation

    A diagram in the notation consists of several shapes linked together by lines. The notation widely appears in modern quantum theory, particularly in matrix product states and quantum circuits. In particular, categorical quantum mechanics (which includes ZX-calculus) is a fully comprehensive reformulation of quantum theory in terms of Penrose ...

  9. Common rail (electricity) - Wikipedia

    en.wikipedia.org/wiki/Common_rail_(electricity)

    In electrical engineering, a common rail (shortened to COM) is a shared path between different electrical routes in an electrical circuit.For example, a device or circuit board might have a power rail or a ground rail, which components are attached to, so all the electrical charge flowing through different components is drawn from/collected into a single conductor line.
