Signal library

Toolkit for signal library.

For a quick introduction, see the topic Libraries of signals for Boulder Opal.

The Boulder Opal Toolkits are currently in beta phase of development. Breaking changes may be introduced.

Graph nodes

Graph nodes to define common operations. You can access them from the signals namespace of a Graph object. For example, to use cosine_pulse_pwc:

qctrl = Qctrl()
graph = qctrl.create_graph()
graph.signals.cosine_pulse_pwc(...)

Following is a list of graph nodes in the signals toolkit:

cosine_pulse_pwc	Create a Pwc representing a cosine pulse.
gaussian_pulse_pwc	Create a Pwc representing a Gaussian pulse.
gaussian_pulse_stf	Create an Stf representing a Gaussian pulse.
hann_series_pwc	Create a Pwc representing a sum of Hann window functions.
hann_series_stf	Create an Stf representing a sum of Hann window functions.
linear_ramp_pwc	Create a Pwc representing a linear ramp.
linear_ramp_stf	Create an Stf representing a linear ramp.
sech_pulse_pwc	Create a Pwc representing a hyperbolic secant pulse.
sech_pulse_stf	Create an Stf representing a hyperbolic secant pulse.
sinusoid_pwc	Create a Pwc representing a sinusoidal oscillation.
sinusoid_stf	Create an Stf representing a sinusoidal oscillation.
square_pulse_pwc	Create a Pwc representing a square pulse.
tanh_ramp_pwc	Create a Pwc representing a hyperbolic tangent ramp.
tanh_ramp_stf	Create an Stf representing a hyperbolic tangent ramp.

Functions

Methods to perform common tasks. You can access them from the signals namespace of the Qctrl object. For example, to use cosine_pulse:

qctrl = Qctrl()
qctrl.signals.cosine_pulse(...)

Following is a list of functions in the signals toolkit:

cosine_pulse	Create a Signal object representing a cosine pulse.
gaussian_pulse	Create a Signal object representing a Gaussian pulse.
hann_series	Create a Signal object representing a sum of Hann window functions.
linear_ramp	Create a Signal object representing a linear ramp.
sech_pulse	Create a Signal object representing a hyperbolic secant pulse.
sinusoid	Create a Signal object representing a sinusoidal oscillation.
square_pulse	Create a Signal object representing a square pulse.
tanh_ramp	Create a Signal object representing a hyperbolic tangent ramp.

Classes

Classes to store common data types for the methods in the toolkit. You can access them from the signals namespace of the Qctrl object. For example, to use SegmentationType:

qctrl = Qctrl()
qctrl.signals.SegmentationType(...)

Following is a list of classes in the signals toolkit:

SegmentationType	An enumeration of segmentation types for piecewise-constant signals.
Signal	A class that contains information about a signal that can be discretized.
