'''Large-signal modeling''' is a common analysis method used in [[electronic engineering]] to describe nonlinear devices in terms of the underlying [[Nonlinearity|nonlinear]] equations.

In [[Electronic circuit|circuit]]s containing nonlinear elements such as [[transistor]]s, [[diode]]s, and [[vacuum tube]]s, under "large signal conditions", AC signals have high enough magnitude that nonlinear effects must be considered.

"Large signal" is the opposite of "[[Small-signal model|small signal]]", which means that the circuit can be reduced to a linearized equivalent circuit around its operating point with sufficient accuracy.
