Description

Class Summary

BandlimitedNoise	This actor generates continuous-time noise with a Gaussian distribution and controlled bandwidth.
ContinuousMerge	A merge actor for the Continuous domain.
ContinuousTimeDelay	Delay the input by a specified amount of time.
ContinuousTransferFunction	A transfer function in the continuous time domain.
DifferentialSystem	A differential system in the Continuous domain.
DiscreteClock	Deprecated. Use ptolemy.actor.lib.DiscreteClock instead.
EventSource	Deprecated. Use with period set to Infinity
Integrator	The integrator in the continuous domain.
LevelCrossingDetector	An event detector that converts continuous signals to discrete events when the input trigger signal crosses a threshold specified by the level parameter.
LinearStateSpace	Linear state space model in the CT domain.
Noise	This actor generates continuous-time noise with a Gaussian distribution.
PeriodicSampler	This actor generates discrete events by periodically sampling the input signal.
ZeroOrderHold	Convert discrete events at the input to a continuous-time signal at the output by holding the value of the discrete event until the next discrete event arrives.

Notes about converting models from the ct domain to the continuous domain

The script $PTII/ptolemy/domains/continuous/lib/ct2continous attempts to convert CT domain models and Java files to the Continuous domain.

1. Change domains.fsm to domains.modal
2. domains.ct.kernel.CTMixedSignalDirector (and all other directors) should be change to domains.continuous.kernel.ContinuousDirector
3. Director class for modal models may need to be changes
4. If the ct model has an ODESolver present, then delete it and use the default
5. Change domains.ct.lib.CTPeriodicSampler to domains.continuous.lib.PeriodicSampler
6. Change CTEmbedded director to domains.continuous.kernel.ContinuousDirector and remove any ODESolver.
7. Change ZeroCrossing to LevelCrossingDetector
8. Integrator: port names change
   • input to derivative.
   • output to state
9. Remove any EditorIcons
