• A linear time-invariant circuit containing R, L, C, M, linear
dependent sources and a single input source is described by a
linear ordinary differential equation with constant coefficients.
The differential equation for such a circuit can be expressed in
a standard format as below:
• The order of a circuit is equal to the order of the differential
equation that describes it. The order of the circuit will be equal
to the total number of independent inductors and capacitors –
the number of all-inductor nodes – the number of all-capacitor
loops in the circuit.
• The natural response of a linear time-invariant
circuit contains n complex exponential functions ...
