qc_open_library('quarc_library/Discontinuities')Description
The Threshold block compares an input to the threshold. Specify how the comparison is done by selecting Relational operator from menu. Also the block records the time where the comparison is true, and checks if the time is within the specified Duration.
Input Ports
signal
Input signal.
threshold
The threshold for comparison. This port only appears when Source of parameters is set to
External input port.
duration
Time (in s) the comparison is true. This port only appears when Source of parameters is set to
External input port.
Output Ports
elapsed
Outputs 1 if the time of comparison being true exceeds the duration, otherwise 0.
time
Time the comparison being true. This time resets itself every time the comparison switches from true to false.
Parameters and Dialog Box
Relation operator
Select one of the following operators,
>, >=, <, <=,==, and ~=.
Source of parameters
Specifies the source of parameters of the selected controller. The options are
Specify via dialog and External input port.
Threshold (tunable online)
