Constant¶

class Constant(duration, amp, name=None, limit_amplitude=None)[ソース]¶

ベースクラス: qiskit.pulse.library.parametric_pulses.ParametricPulse

A simple constant pulse, with an amplitude value and a duration:

\[f(x) = amp , 0 <= x < duration f(x) = 0 , elsewhere\]

Initialize the constant-valued pulse.

パラメータ

duration (Union[int, ParameterExpression]) – Pulse length in terms of the the sampling period dt.
amp (Union[complex, ParameterExpression]) – The amplitude of the constant square pulse.
name (Optional[str]) – Display name for this pulse envelope.
limit_amplitude (Optional[bool]) – If True, then limit the amplitude of the waveform to 1. The default is True and the amplitude is constrained to 1.

Methods

`draw`	Plot the interpolated envelope of pulse.
`get_waveform`	Return a Waveform with samples filled according to the formula that the pulse represents and the parameter values it contains.
`is_parameterized`	Return True iff the instruction is parameterized.
`validate_parameters`	Validate parameters.

Attributes

amp¶

The constant value amplitude.

Unique identifier for this pulse.
