TimeSegment

class TimeSegment(start, end, pulses)

Represents a time segment associated with a list of pulses.

A TimeSegment is a time interval and includes all pulses that are active in the interval. It based on the PulseList and provides additional metadata relevant for plotting and simulation.

Initialize a time segment.

Parameters:

• start – Start time of the segment.

• end – End time of the segment.

• pulses – Active pulses corresponding to the segment.

Methods

append(new_pulse)	Appending a pulse is disabled for TimeSegment instances.
convert_to_time_segment_sequence([start, end])	Convert the to TimeSegmentSequence.
discretize_plot(function)	Discretize the time segment for plotting.
discretize_simulation(...[, n_eval, n_split])	Discretize the time segment for simulation.
signal([driving_field_name])	Return the signal to be used in simulation.

Attributes

duration	Duration of the time segment.
end	End time of the segment.
is_all_constant_envelope	Check if all pulses have a constant envelope.
max_frequency	Maximal frequency of the time segment's pulses.
n_pulses	Number of pulses.
