Boolean Change

Indicates Boolean signal changing

 Description The output is $\mathrm{true}$ if the Boolean input has either a rising edge from $\mathrm{false}$ to $\mathrm{true}$ or a falling edge from $\mathrm{true}$ to $\mathrm{false}$, otherwise the output is $\mathrm{false}$. The output is $\mathrm{true}$ only for an instant, so a plot of it will always appear $\mathrm{false}$.
 Equations $y=\mathrm{change}\left(u\right)$
