Definition
An electronic circuit whose output frequency is a whole-number multiple of its input frequency. A multiplier takes a stable lower-frequency signal and produces a higher-frequency signal that is two, three, or more times the original, while preserving the timing relationship to the input.
Plain English
A circuit that takes one signal coming in and puts out a signal at a higher rate -- exactly two times, three times, or more times faster than the one going in.
Context Anchor
Seen in aircraft electrical system troubleshooting, especially when discussing how meters measure voltage ranges.
Derivation
From the Latin 'multiplicare,' meaning 'to increase many times.' The name fits: the circuit multiplies the input frequency by a fixed whole number.
Why Pilots Care
A pilot or mechanic using the wrong meter range can damage the meter or get a bad reading, so understanding a multiplier helps make sense of electrical test equipment limits.
Analogy
It is like adding a larger scale to a measuring tool so it can handle a bigger value without being pushed past its limit.
Intuition Check
Do not read multiplier here as a person or device that simply makes electrical power stronger. In this context, it is a resistor that lets a meter measure a higher voltage safely.
Example Sentence 1
The transmitter uses a frequency multiplier to step the oscillator's signal up to the operating frequency.
Example Sentence 2
Without the correct multiplier the meter movement would be destroyed by excess voltage.
