Multiplier

Multiplier may refer to:

Mathematics

• Multiplier (coefficient), the number of multiples being computed in multiplication, also known as a coefficient in algebra
• Lagrange multiplier, a scalar variable used in mathematics to solve an optimisation problem for a given constraint
• Multiplier (Fourier analysis), an operator that multiplies the Fourier coefficients of a function by a specified function (known as the symbol)
• Multiplier of orbit, a formula for computing a value of a variable based on its own previous value or values
• Characteristic multiplier, an eigenvalue of a monodromy matrix
• Multiplier algebra, a construction on C*-Algebras and similar structures

Electrical engineering

• Binary multiplier, a digital circuit to perform rapid multiplication of two numbers in binary representation
• Analog multiplier, a device that multiplies two analog signals
• Frequency multiplier, a device that generates a signal at an integer multiple of its input frequency* multiplier, a device that provides a high resistance in order to drop excess voltage, allowing voltmeter to read a potential difference that is greater than that which would produce the FULL SCALE DEFLECTION (FSD) current in the meter.

Macroeconomics

• Multiplier (economics), any measure of the proportional effect of an exogenous variable on an endogenous variable
• Fiscal multiplier, the ratio of the change in aggregate demand to the change in government spending that caused it
• Money multiplier, the ratio of the money generated by the banking system to the central bank's increase in the monetary base that caused it

Others

• Force multiplier, in warfare a factor that dramatically increases the combat-effectiveness of a given military force
• A multiplier fishing reel creates less friction when casting
• A CPU multiplier allows a CPU to perform more cycles per single cycle of the front side bus
• Multiplier (linguistics), an adjective indicating number of times something is to be multiplied
