Soon to enter into a continuous-time systems time domain analysis study, do you remember the classic solution of linear differential equations with constant coefficients do
not remember it does not matter, even if the classical solution of linear differential equations with constant abandoned you, do not be sad, do not be discouraged, Well we could go over it (funny)
Well, let's give an example review the classical solution of linear differential equations with constant bar
1. the classic solution
by the characteristic roots homogeneous solution can be obtained in the form of characteristic
function form and function of special solutions incentives form about
you recall now how to do it him? Maybe you did not recall (funny), we have to write a good example
The original recall just so tired, exhausted me, but. . Do you think I'll fall right? Do not! Help me up! I can continue to learn!
The change we are not familiar, learned the circuit's friends have said the Easy SO
But! We are here signals and systems, I would say that with the impulse function matching method to solve this problem
first of all we have seen thrown in the circuit a circuit many times (it is no matter many times, especially for such slag slag is I (tears))
and has reached a given circuit shown in FIG., t <0 1 switch S in the steady state position; when t = 0, S 1 by the steering 2. Which solving i (0+) and d / dt (i0 +)
Of course, when we learned before the circuit, we also participated voltage across the capacitor and the inductor current does not occur to solve this problem by using a mutation.
But now we learn signals and systems we impulse function matching method to solve this problem (impulse function is a good thing, if there is no impulse function, more complex circuits to be analyzed in this rookie long time to write (manual nugget) )
really learn not move (a head)
(probably recently at home for too long, he began to lose your head .......)
