  2. Superposition principle - Wikipedia

    en.wikipedia.org/wiki/Superposition_principle

    The superposition principle, [1] also known as superposition property, states that, for all linear systems, the net response caused by two or more stimuli is the sum of the responses that would have been caused by each stimulus individually.

  3. Linear circuit - Wikipedia

    en.wikipedia.org/wiki/Linear_circuit

    A linear circuit is an electronic circuit which obeys the superposition principle.This means that the output of the circuit F(x) when a linear combination of signals ax 1 (t) + bx 2 (t) is applied to it is equal to the linear combination of the outputs due to the signals x 1 (t) and x 2 (t) applied separately:

  4. Zero state response - Wikipedia

    en.wikipedia.org/wiki/Zero_state_response

    In electrical circuit theory, the zero state response (ZSR) is the behaviour or response of a circuit with initial state of zero. The ZSR results only from the external inputs or driving functions of the circuit and not from the initial state. The total response of the circuit is the superposition of the ZSR and the ZIR, or Zero Input Response ...

  5. Linear time-invariant system - Wikipedia

    en.wikipedia.org/wiki/Linear_time-invariant_system

    The defining properties of any LTI system are linearity and time invariance.. Linearity means that the relationship between the input () and the output (), both being regarded as functions, is a linear mapping: If is a constant then the system output to () is (); if ′ is a further input with system output ′ then the output of the system to () + ′ is () + ′ (), this applying for all ...

  6. Small-signal model - Wikipedia

    en.wikipedia.org/wiki/Small-signal_model

    Small-signal modeling is a common analysis technique in electronics engineering used to approximate the behavior of electronic circuits containing nonlinear devices with linear equations. It is applicable to electronic circuits in which the AC signals (i.e., the time-varying currents and voltages in the circuit) are small relative to the DC ...

  7. Linear system - Wikipedia

    en.wikipedia.org/wiki/Linear_system

    The superposition principle means that a linear combination of inputs to the system produces a linear combination of the individual zero-state outputs (that is, outputs setting the initial conditions to zero) corresponding to the individual inputs.

  8. Network analysis (electrical circuits) - Wikipedia

    en.wikipedia.org/wiki/Network_analysis...

    In electrical engineering and electronics, a network is a collection of interconnected components. Network analysis is the process of finding the voltages across, and the currents through, all network components. There are many techniques for calculating these values; however, for the most part, the techniques assume linear components.

  9. Coulomb's law - Wikipedia

    en.wikipedia.org/wiki/Coulomb's_law

    However, Gauss's law can be proven from Coulomb's law if it is assumed, in addition, that the electric field obeys the superposition principle. The superposition principle states that the resulting field is the vector sum of fields generated by each particle (or the integral, if the charges are distributed smoothly in space).
