In general an amplification factor is the numerical multiplicative factor by which some quantity is increased.
* In
structural engineering
Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and muscles' that create the form and shape of man-made structures. Structural engineers also must understand and cal ...
the amplification factor is the ratio of second order to first order
deflections.
* In electronics the amplification factor, or
gain, is the ratio of the output to the input of an
amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It may increase the power significantly, or its main effect may be to boost t ...
, sometimes represented by the symbol A
F.
* In
numerical analysis
Numerical analysis is the study of algorithms that use numerical approximation (as opposed to symbolic manipulations) for the problems of mathematical analysis (as distinguished from discrete mathematics). It is the study of numerical methods ...
the amplification factor is a number derived using
Von Neumann stability analysis
The term ''von'' () is used in German language surnames either as a nobiliary particle indicating a noble patrilineality, or as a simple preposition used by commoners that means ''of'' or ''from''.
Nobility directories like the ''Almanach de Go ...
to determine stability of a numerical scheme for a
partial differential equation.
