Advanced | SIDSEUIL
OVERSHOOT TIME – [SIDSEUIL]
Computes the period of time during which a threshold value is reached in a signal.
CATEGORY
Advanced
DESCRIPTION
The function computes the period of time and different results related to the overshoot time during which a threshold value is reached in a signal, either on a rising or a falling edge(Slope).
It computes the beginning and ending time and duration of the threshold condition.
To perform the analysis, a new signal is generated with the three signals specified as input parameters and following the type of threshold specified.
Based on the slope value, resulting signal calculated as follow:
| Rise(m) | Resulting signal is the maximum of the three signals. |
|---|---|
| Fall(d) | Resulting signal is the minimum of the three signals. |
When samples do not belong to the signal part specified, values are replaced by 0.0.
User must specify three input signals. However, if only one signal is to be used, then the same name should be given to all three signals. When only one signal is processed, the maximum and minimum samples will result in one identical signal. Similarly, if two signals are to be processed, the third signal to be used can be identical to one of the first two.
RESULT VARIABLES AND PARAMETERS
| tsed | From the starting time of the analysis, course of the generated signal to find the time at which the threshold value is reached based on the type of threshold specified. The time is returned in milliseconds [ms] and is relative to time 0. | ||||||||
| tsef | From the ending time of the analysis, course of the generated signal towards the beginning to find the time at which the threshold value is reached based on the type of threshold specified. The time is returned in milliseconds [ms] and is relative to time 0. | ||||||||
| duse | Difference between tsef and tsed in milliseconds [ms]. This result represents the period of time during which the threshold value is reached. | ||||||||
| Signal_1 | First signal to analyze. | ||||||||
| Signal_2 | Second signal to analyze. | ||||||||
| Signal_3 | Third signal to analyze. | ||||||||
| Signal_Part | Part of the signal on which the analysis is done (neg, pos, sig, abs). Here are the definitions of the four distinct parts of a signal:
| ||||||||
| Threshold | Value of threshold to be reached on the specified part of the signal. | ||||||||
| Slope | Type of threshold to reach: the threshold value can be reached on a rise (m) or a fall (d).
| ||||||||
| Begin_time | Time at which the analysis of a signal must start. This time is expressed in milliseconds [ms]. This value must be greater than 0 and lower than the duration of the test. The default value is 0. | ||||||||
| End_time | Time at which the analysis of a signal must end. This time is expressed in milliseconds [ms]. The value of this time must be larger than the specified begin_time and smaller than the duration of the test. Use the “HUGE” value to specify the end of the test. The default value is HUGE. | ||||||||
| Factor | Multiplying factor for the results generated by the function. The default value of the multiplying factor is 1.0 and has no effect on the results. The multiplying factor applies only to the tsed and tsef results.It does not apply to the duse result. |
