impulse function. This is achieved by using the method given in
Chapter 5, specifically, by evaluating the following integral

Because

and

If the switching variable of the diode contains a Dirac im-
pulse. Otherwise, only consistent initial conditions will be encoun-
tered at the switching instant. The consistent initial condition
is obtained by employing the two-step algorithms given in Chapter
5. Once and are available, the switching variable of the
diode given by is evaluated at In this case,
since and is non-zero, an impulsive
forward biasing voltage exists across the diode and the diode turns
