  2. Multimeter - Wikipedia

    en.wikipedia.org/wiki/Multimeter

    Analog multimeter Digital multimeter. A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [2] [3] A typical multimeter can measure voltage, resistance, and current, [4] in which case can be used as a voltmeter, ohmmeter, and ammeter.

  3. True RMS converter - Wikipedia

    en.wikipedia.org/wiki/True_RMS_converter

    Distortion of a waveform True RMS Multimeter For the measurement of an alternating current the signal is often converted into a direct current of equivalent value, the root mean square (RMS). Simple instrumentation and signal converters carry out this conversion by filtering the signal into an average rectified value and applying a correction ...

  4. ESR meter - Wikipedia

    en.wikipedia.org/wiki/ESR_meter

    Measuring ESR can be done by applying an alternating voltage at a frequency at which the capacitor's reactance is negligible, in a voltage divider configuration. It is easy to check ESR well enough for troubleshooting by using an improvised ESR meter comprising a simple square-wave generator and oscilloscope, or a sinewave generator of a few tens of kilohertz and an AC voltmeter, using a known ...

  5. Honeywell 6000 series - Wikipedia

    en.wikipedia.org/wiki/Honeywell_6000_series

    The 6000-series machine's basic instruction set has more than 185 single-address one-word instructions. [11] The basic instructions are one word; the instruction format is an extension of that of the GE-600 series , with the opcode field extended to 10 bits by adding bit 27 as the low-order bit; that bit is zero in all GE-600 series instructions.

  6. Analog multiplier - Wikipedia

    en.wikipedia.org/wiki/Analog_multiplier

    As digital technology advances, the use of analog multipliers tends to be ever more marginalized towards higher-frequency circuits or very specialized applications. In addition, most signals are now destined to become digitized sooner or later in the signal path, and if at all possible the functions that would require a multiplier tend to be ...

  7. VAX 6000 - Wikipedia

    en.wikipedia.org/wiki/VAX_6000

    The Model 600 used the KA66A CPU module, which contained an 83.33 MHz (12 ns cycle time) NVAX microprocessor accompanied by an external 2 MB B-cache (L2 cache) and may have one to six such modules. The NVAX was connected to the NEXMI ASIC via the NDAL bus, a 64-bit address data multiplexed system bus clocked at 27.78 MHz (36 ns cycle time).

  9. Full scale - Wikipedia

    en.wikipedia.org/wiki/Full_scale

    The amplitude of a digital signal can be represented in percent; full scale; or decibels, full scale (dBFS). In analog systems, full scale may be defined by the maximum voltage available, or the maximum deflection ( full scale deflection or FSD ) or indication of an analog instrument such as a moving coil meter or galvanometer .
