Designed a second order differential equation of y (t) + "a1y '(t) + a0 y (t)=e (t) with a1, a2 as optional constant, set up by the students themselves. Boundary conditions (0 -) y, y '(0 -) given by the students themselves; Incentive optional index sequences, step sequence, sine sequence, sequence parameters set by oneself, according to the difference equations, boundary conditions and the specific incentive sequence simulation and zero input response of the system, zero state response and total response, continuous waveform ()
