1.1 Time-space analysis

The analysis of a linear circuit with localized constants leads to the solution of a linear differential equation with constant coefficients (article [E100v2] § 1.6.1.). Solving this equation is often difficult: first, you have to find the general solution of the equation without a second member, then calculate a solution of the equation with a second member and determine, taking into account the initial conditions, the constants involved in expressing the general solution....
