  2. Test probe - Wikipedia

    en.wikipedia.org/wiki/Test_probe

    The insulation is chosen to be both flexible and have a breakdown voltage higher than the voltmeter's maximum input voltage. The many fine strands and the thick insulation make the wire thicker than ordinary hookup wire. Two probes are used together to measure voltage, current, and two-terminal components such as resistors and capacitors.

  3. Voltage-controlled resistor - Wikipedia

    en.wikipedia.org/wiki/Voltage-controlled_resistor

    The input-port voltage controls the value of the resistor between the output ports. VCRs are most often built with field-effect transistors (FETs). Two types of FETs are often used: the JFET and the MOSFET. There are both floating voltage-controlled resistors and grounded voltage-controlled resistors. Floating VCRs can be placed between two ...

  4. Oscilloscope - Wikipedia

    en.wikipedia.org/wiki/Oscilloscope

    In the case of digital oscilloscopes, an analog-to-digital converter (ADC) changes the measured voltages into digital information. The digital storage oscilloscope, or DSO for short, is the standard type of oscilloscope today for the majority of industrial applications, and thanks to the low costs of entry-level oscilloscopes even for hobbyists.

  5. Electronic paper - Wikipedia

    en.wikipedia.org/wiki/Electronic_paper

    Flexible electronic paper uses plastic substrates and plastic electronics for the display backplane. Applications of e-paper include electronic shelf labels and digital signage, [3] bus station time tables, electronic billboards, [4] smartphone displays, and e-readers able to display digital versions of books and magazines.

  6. Voltmeter - Wikipedia

    en.wikipedia.org/wiki/Voltmeter

    Analog voltmeters move a pointer across a scale in proportion to the voltage measured and can be built from a galvanometer and series resistor. Meters using amplifiers can measure tiny voltages of microvolts or less. Digital voltmeters give a numerical display of voltage by use of an analog-to-digital converter.

  7. Comparison of display technology - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_display...

    Single-chip DLPs use a kind of "chromatic multiplexing" in which each color is presented serially. The intensity is varied by modulating the "on" time of each pixel within the time-span of one color. Multi-chip DLPs are not represented in this sketch, but would have a curve identical to the plasma display.

  8. Counter (digital) - Wikipedia

    en.wikipedia.org/wiki/Counter_(digital)

    Voltage changes on the five outputs of the binary counter counting from 00000, left to 11111 (or 31), right (vertically). In digital logic and computing , a counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock .

  9. Joint Electronics Type Designation System - Wikipedia

    en.wikipedia.org/wiki/Joint_Electronics_Type...

    The Joint Electronics Type Designation System (JETDS), which was previously known as the Joint Army-Navy Nomenclature System (AN System. JAN) and the Joint Communications-Electronics Nomenclature System, is a method developed by the U.S. War Department during World War II for assigning an unclassified designator to
