Example:zerocrossrate(x,InitialState=[1 0 –1 3])returns the crossing rates of a four-channel input signalx. Data Types:single|double|int8|int16|int32|int64|uint8|uint16|uint32|uint64 Method—Method for computing zero-crossing rate ...
and the decrease of the zero crossing rate of vertical component is more obvious with the increase of time;(2)irregular terrain will increase the Wenchuan ground motion zero-crossing rate of non-stationary;(3)compared with the vertical component, the horizontal component attenuation change is small...

Implementation Example: Saturation Block An example of a Simulink block that registers zero crossings is the Saturation block. Zero-crossing detection identifies these state events in the Saturation block: The input signal reaches the upper limit. The input signal leaves the upper limit. The input ...
27. After developing the technique on a dataset of long-term simultaneous scalp and intracranial recordings we confirm its practical clinical applicability on an independent scalp EEG dataset. Our results suggest that scalp zero-crossing patterns extract the spatiotemporal structure of subtle scalp ...
Also consecutive occurrences of the value whose crossings are sought, are assigned to the last occurrence before the crossing (see last example). EXAMPLES 1. Assume that VALUE=0, X(4)=-2 and X(5)=3. Then - 'dis' will assign the 0-crossing to n=4, - 'pre' will assign the 0...
Methods and systems for detection of zero crossings in a signal are described. For example, true zero crossings in an alternating voltage power source signal can be detected in the presence of noise pulses. The zero crossing detections are performed by establishing a value of a signal status ...
The zero-crossing identification circuit includes a pulse delay unit which is tuned to the mains frequency. A third monostable multivibrator (M3) is provided with a working time, which lies between the cycles of the smaller and the larger mains frequency, for the differentiation of a smaller and...
