systest.signals.Signal - Collection of segments used to generate time-based data

Syntax

Description

systest.signals.Signal('segment_type') creates a signal with a segment of type segment_type.

The following properties can be used on the systest.signals.Signal function:

• DataType – The class of time-based data that will be generated.

• Duration – The ending point of the Time vector.

• ExtrapolationMode – Used to determine Data values after the endpoint of the last Segmentl.

• Segments – An array of Segment objects inside this Signal.

• Time – The Time vector of the Signal.

• Data – The Data vector of the Signal.

The following static functions can be used with the systest.signals.Signal function:

• getAvailableExtrapolationModes – Returns a list of valid values for ExtrapolationMode property.

• getAvailableDataTypes – Returns a list of valid values for DataType property.

Examples

Create a signal with a Step segment followed by a Pulse.

systest.signals.Signal('Step', 'Pulse')

Create a signal with custom user data.

time = [0:.1:10]';
data = rand(length(time), 1);
systest.signals.Signal('Custom', {'Time', time, 'Data', data'}))
