Detects zero crossings of an integer input signal.

Use the pull-down menu to select an instance of this VI.

Zero Crossing (I16)

initialize, when TRUE, stores input and sets crossing to FALSE. The VI initializes automatically when you first call it in a VI.
input is the data point the VI processes.
direction is the kind of zero crossing. You can choose from the following settings: either, minus-plus, or plus-minus.
crossing is TRUE if a zero crossing occurred.

Zero Crossing (I8)

initialize, when TRUE, stores input and sets crossing to FALSE. The VI initializes automatically when you first call it in a VI.
input is the data point the VI processes.
direction is the kind of zero crossing. You can choose from the following settings: either, minus-plus, or plus-minus.
crossing is TRUE if a zero crossing occurred.

Zero Crossing (I32)

initialize, when TRUE, stores input and sets crossing to FALSE. The VI initializes automatically when you first call it in a VI.
input is the data point the VI processes.
direction is the kind of zero crossing. You can choose from the following settings: either, minus-plus, or plus-minus.
crossing is TRUE if a zero crossing occurred.
