SquareTest

Usage

SquareTest()

Behavior

\[ \begin{align} \mathtt{signal.y}\left( t \right) &= \mathtt{integrator.u}\left( t \right) \\ \frac{\mathrm{d} \mathtt{integrator.x}\left( t \right)}{\mathrm{d}t} &= \mathtt{integrator.k} \mathtt{integrator.u}\left( t \right) \\ \mathtt{integrator.y}\left( t \right) &= \mathtt{integrator.x}\left( t \right) \\ \mathtt{signal.y}\left( t \right) &= ifelse\left( \mathtt{signal.start\_time} < t, \mathtt{signal.offset} + \mathtt{signal.amplitude} \left( 1 + 4 \left\lfloor \mathtt{signal.frequency} \left( - \mathtt{signal.start\_time} + t \right)\right\rfloor - 2 \left\lfloor 2 \mathtt{signal.frequency} \left( - \mathtt{signal.start\_time} + t \right)\right\rfloor \right), \mathtt{signal.offset} \right) \end{align} \]
