A network containing at least one non-linear element, where the relationship between voltage and current is not linear.

A network composed entirely of passive elements (resistors, capacitors, inductors) that cannot generate energy but can store energy.

A network where the electrical properties vary with position and time, meaning the parameters cannot be concentrated at specific locations.

A source that can supply an unlimited amount of energy without any internal resistance or voltage drop.

A source that can supply an unlimited amount of current without any internal resistance or change in voltage.

A source that has a limited ability to supply energy due to internal resistance or voltage drop.

A source that has a limited ability to supply current due to internal resistance or change in voltage.

A method of analyzing a circuit by applying Kirchhoff's Current Law (KCL) at each node in the circuit. The node equations are then solved to determine the unknown node voltages.

This theorem states that when transferring power from a source to a load, maximum power is delivered to the load when the load impedance is matched or the complex conjugate of the source impedance, leading to the most efficient power transfer.

A method of circuit analysis that involves finding the equivalent impedance of a circuit by converting a star network to a delta network or vice versa. This is helpful in simplifying complex circuits.

A method of circuit analysis that states that the total current through a linear circuit is equal to the sum of the currents that would flow if each source were considered independently with all other sources set to zero.

A mathematical tool used to analyze and solve linear circuits by transforming time-domain functions into frequency-domain functions, simplifying the calculation and understanding of the circuit's behavior.

The initial response of a circuit to a change in input, usually represented as an exponential function, which indicates how quickly the system reacts to the change.

The steady-state response of a circuit to a change in input, usually represented by a constant or periodic function, describing the long-term behavior of the circuit after transients have settled.

A function representing a gradual, linear increase in value over time. It is used in circuit analysis to represent a constant rate of change in voltage or current.

A function representing a concentrated spike of short duration. It has an infinite amplitude and a zero duration, indicating instantaneous change.

A function representing a constant value of 1 starting from a certain time point. It's used to represent a sudden change in input or output.

A function representing a constant value of 0 for negative times and a constant value of 1 for positive times. It is used to model the onset of signals or changes in systems.

The solution to a differential equation representing the behavior of a circuit that is independent of the initial conditions. It describes the general trend of the system's response.

The solution to a differential equation representing the behavior of a circuit that accounts for the specific initial conditions of the system. It describes the exact response of the system based on its starting point.

The parameters that describe the relationship between the input and output voltages and currents of a two-port network. Y parameters represent the admittance matrix, which is the inverse of the impedance matrix (Z parameters).

The parameters that describe the relationship between the input and output voltages and currents of a two-port network. Z parameters represent the impedance matrix, which is the inverse of the admittance matrix (Y parameters).

A type of resonance that occurs in a parallel RLC circuit, characterized by impedance reaching a maximum value at resonant frequency. The current is minimum at resonance, with voltage maximized.

The graph of the amplitude of the output signal of a filter as a function of frequency.

The frequency at which a filter's output signal falls to 3 dB below its maximum value. It defines the boundary between the passband and stopband.

The range of frequencies that a filter allows to pass through with minimal attenuation. It typically describes the frequencies where the signal is least distorted.

A type of filter that passes low-frequency signals and attenuates high-frequency signals. It is characterized by a gradual roll-off in the stopband.

The ability of a circuit to store energy in an electric field. It is measured in Farads.

The property of a circuit to resist changes in current flow. It is measured in Henries.

A type of circuit that has a single energy storage element (capacitor or inductor). It can be characterized by a single time constant, determining its response time.

A type of circuit that has two energy storage elements (capacitor and inductor). It can be characterized by two time constants, determining its more complex response time.
