multiplier

- A circuit or device which multiplies a
__number__of pulses, cycles, signals, or other input quantity, by a fixed number, such as 2 or 10. For example, electron, frequency, or voltage multipliers. - An electron tube in which secondary electron emissions produce
__current amplification__. In it, a__cathode__releases primary electrons, which are then reflected by multiple electron mirrors, or dynodes, each producing more and more electrons. Depending on the number of dynodes, the amplification factor may be in the millions. Also called__electron multiplier__, or secondary electron multiplier. - A circuit or device whose
__output____signal frequency__is an exact integer multiple of its input__signal__frequency. For example, such a circuit could convert a 10 MHz signal into a 30 MHz signal with the use of a frequency tripler. Also called__frequency multiplier__. - A component or circuit whose voltage output is a multiple of its input voltage. For example, a
__rectifier circuit__which delivers a__DC____output voltage__which is a multiple of the__peak__of its input__AC voltage__. Also called__voltage multiplier__(1). - A
__precision____resistor__utilized in series, to extend the voltage range of an instrument such as a__voltmeter__. Also called multiplier resistor, or voltage-range multiplier (2). - An already present number by which another is multiplied. A
__multiplicand__is a newly introduced number which multiplies the multiplier. For instance, in 13 × 3, the multiplier is 13, while the multiplicand is 3.
