Summary
- Plugin name : Zero-Crossing Detector
- Version : 1.0
- Author : Quentin Barthelemy
- Company : Mensia Technologies SA
- Short description : Detects zero-crossings of the signal
- Documentation template generation date : Jan 9 2018
Description
Detects zero-crossings of the signal for each channel, with 1 for positive zero-crossings (negative-to-positive), -1 for negatives ones (positive-to-negative), 0 otherwise. For all channels, stimulations mark positive and negatives zero-crossings. For each channel, the rythm is computed in events per min.
Using an hysteresis thresholding, this box detects the zero-crossings of the input, operating on all channels.
Inputs
1. Input signal
The input signal , composed of sensors and samples.
- Type identifier : Signal (0x5ba36127, 0x195feae1)
Outputs
1. Zero-crossing signal
Zero-crossing signal , composed of sensors and samples. It is defined as 1 for positive zero-crossings (negative-to-positive), -1 for negatives ones (positive-to-negative), 0 otherwise.
- Type identifier : Signal (0x5ba36127, 0x195feae1)
2. Zero-crossing stimulations
For all channels, stimulations mark positive and negatives zero-crossings.
- Type identifier : Stimulations (0x6f752dd0, 0x082a321e)
3. Events rythm (per min)
For each channel, the rythm of zero-crossings is computed in events per min.
- Type identifier : Streamed matrix (0x544a003e, 0x6dcba5f6)
Settings
1. Hysteresis threshold
This setting defines the value of the hysteresis threshold, to provide a robust detection.
- Type identifier : Float (0x512a166f, 0x5c3ef83f)
- Default value : [ 0.01 ]
2. Rythm estimation window (in sec)
This setting defines the length of the time window for the rythm estimation.
- Type identifier : Float (0x512a166f, 0x5c3ef83f)
- Default value : [ 10 ]
3. Negative-to-positive stimulation
This setting defines the stimulation id for negative-to-positive crossings.
- Type identifier : Stimulation (0x2c132d6e, 0x44ab0d97)
- Default value : [ OVTK_StimulationId_ThresholdPassed_Positive ]
4. Positive-to-negative stimulation
This setting defines the stimulation id for positive-to-negative crossings.
- Type identifier : Stimulation (0x2c132d6e, 0x44ab0d97)
- Default value : [ OVTK_StimulationId_ThresholdPassed_Negative ]
