# multiplier

## Definitions

### Accounting

### Construction

- A factor used to adjust costs for modifications, such as for location,
__time__, or __size__ of project.

### Economics

- noun a factor which tends to multiply something, as when the effect of new inputs such as investment is to produce a proportionately higher increase in national income

### Electronics

- 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.
