Square

Generate square signal.

This component extends from Signal

Usage

Square(start_time=0.0, offset=0.0, amplitude, frequency)

Parameters:

Connectors

• y - This connector represents a real signal as an output from a component (RealOutput)

Behavior

\[ \begin{align} y\left( t \right) &= ifelse\left( \mathtt{start\_time} < t, \mathtt{offset} + \mathtt{amplitude} \left( 1 - 2 \left\lfloor 2 \mathtt{frequency} \left( - \mathtt{start\_time} + t \right)\right\rfloor + 4 \left\lfloor \mathtt{frequency} \left( - \mathtt{start\_time} + t \right)\right\rfloor \right), \mathtt{offset} \right) \end{align} \]
