Owning Palette: Nonlinear Systems VIs

Installed With: FPGA Module

Detects zero crossings of an input signal. The data type you wire to input determines the output data type.

The maximum input word length is 32 bits.

	reset, 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.
