square_pulse
- boulderopal.signals.square_pulse(duration, amplitude, start_time=0.0, end_time=None)
Create a Signal object representing a square pulse.
- Parameters:
duration (float) – The duration of the pulse.
amplitude (float or complex) – The amplitude of the square pulse, \(A\).
start_time (float, optional) – The start time of the square pulse, \(t_0\). Defaults to 0.
end_time (float or None, optional) – The end time of the square pulse, \(t_1\). Must be greater than the start time. Defaults to the duration.
- Returns:
The square pulse.
- Return type:

Notes
The square pulse is defined as
\[\mathop{\mathrm{Square}}(t) = A \theta(t-t_0) \theta(t_1-t) ,\]where \(\theta(t)\) is the Heaviside step function.
Examples
Define a square pulse and discretize it.
>>> pulse = bo.signals.square_pulse(duration=4.0, amplitude=2.5, start_time=1.0, end_time=3.0) >>> pulse.export_with_time_step(time_step=1.0) array([0. , 2.5, 2.5, 0. ])
