Generates a step signal

Category: Source

Description:

This block generate a step function signal in its output port. This function is defined by the following equation

y(t)=\begin{cases} x_{i} & t < T_{s} \\ x_{f} & t \geq T_{s}\end{cases}

Where:

$y$
is the output signal.
$x_i$
is the initial value.
$x_f$
is the final value.
$T_s$
is the step time.

Dialog

In the Step Properties dialog, the step amplitude and step time may be configured.

Parameters:

Time in seconds to change output value from initial to final value.

Signal value assigned to the output of the port before the step time.

Signal value assigned to the output of the port after the step time.

Ports:

Input

Generate the step signal according to the Step Properties.
