reset

A Boolean or a Boolean array that determines whether to set crossing to False and store the current input.

True Sets crossing to False and stores the current crossing.
False Does not set crossing to False or store the current crossing.

Default: False

datatype_icon

input

Input signal.

This input accepts a double-precision, floating-point number or an array of double-precision, floating-point numbers.

datatype_icon

direction type

Type of zero crossing.

This input accepts a ring or an array of rings.

Name Value Description
rising 0 Sets crossing to True when the input signal crosses zero on a rising slope.
falling 1 Sets crossing to True when the input signal crosses zero on a falling slope.
either 2 Sets crossing to True when the input signal crosses zero on either a rising or a falling slope.

Default: The default value of this input changes depending on the data type you wire. If you wire a ring to this input, the default is either. If you wire an array of rings to this input, the default is rising.

datatype_icon

cycles to filter

Cycles of the input signal to process.

This input accepts a 64-bit unsigned integer or an array of 64-bit unsigned integers.

Default: 0

datatype_icon

threshold

Threshold to start the measurement.

This input accepts a double-precision, floating-point number or an array of double-precision, floating-point numbers.

Default: 0

datatype_icon

crossing?

A Boolean or a Boolean array that indicates whether a zero crossing occurred.

True A zero crossing occurred.
False No zero crossing occurred.
