  2. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    The tuning application, for instance, is an example of band-pass filtering. The RLC filter is described as a second-order circuit, meaning that any voltage or current in the circuit can be described by a second-order differential equation in circuit analysis. The three circuit elements, R, L and C, can be combined in a number of different ...

    en.wikipedia.org/wiki/Frobenius_method

    Example: consider the following differential equation (Kummer's equation with a = 1 and b = 2): ″ + ′ = The roots of the indicial equation are −1 and 0. Two independent solutions are 1 / z {\displaystyle 1/z} and e z / z , {\displaystyle e^{z}/z,} so we see that the logarithm does not appear in any solution.

  4. Second-order cone programming - Wikipedia

    en.wikipedia.org/wiki/Second-order_cone_programming

    The "second-order cone" in SOCP arises from the constraints, which are equivalent to requiring the affine function (+, +) to lie in the second-order cone in +. [ 1 ] SOCPs can be solved by interior point methods [ 2 ] and in general, can be solved more efficiently than semidefinite programming (SDP) problems. [ 3 ]

  5. Mathematical methods in electronics - Wikipedia

    en.wikipedia.org/wiki/Mathematical_methods_in...

    Mathematical Methods in Electronics Engineering involves applying mathematical principles to analyze, design, and optimize electronic circuits and systems. Key areas include: [1] [2] Linear Algebra: Used to solve systems of linear equations that arise in circuit analysis. Applications include network theory and the analysis of electrical ...

  6. Numerical methods for ordinary differential equations - Wikipedia

    en.wikipedia.org/wiki/Numerical_methods_for...

    For example, the second-order equation y′′ = −y can be rewritten as two first-order equations: y′ = z and z′ = −y. In this section, we describe numerical methods for IVPs, and remark that boundary value problems (BVPs) require a different set of tools. In a BVP, one defines values, or components of the solution y at more than one ...

  7. Lattice network - Wikipedia

    en.wikipedia.org/wiki/Lattice_network

    In the case of the second order network, when a2 > b (i.e. L1 > L2 or C2 > C1 or y > √ 3 x), it is necessary to use the circuit containing mutually coupled coils for the second order all-pass network. A cascade of second order networks with, maybe, a single first order network, can be used to give a high order response. For example, the ...

  8. Power series solution of differential equations - Wikipedia

    en.wikipedia.org/wiki/Power_series_solution_of...

    For example, the next few coefficients: =; =; =; = … A limitation of the power series solution shows itself in this example. A numeric solution of the problem shows that the function is smooth and always decreasing to the left of η = 1 {\displaystyle \eta =1} , and zero to the right.

  9. Integro-differential equation - Wikipedia

    en.wikipedia.org/wiki/Integro-differential_equation

    Integro-differential equations model many situations from science and engineering, such as in circuit analysis. By Kirchhoff's second law, the net voltage drop across a closed loop equals the voltage impressed (). (It is essentially an application of energy conservation.)
