# Limit Specification (Segmented Mask » By Formula) (G Dataflow)

Creates a segmented mask in the time domain or in the frequency domain. This node creates the segmented mask using numerical x-axis values and y-axis values in terms of a formula.  ## reset

A Boolean that determines whether to compute the limit. This node always computes limit the first time it runs.

 True Computes limit using the values in specification. False Does not compute limit.

Default: False ## specification

X-axis and y-axis values at which this node specifies the limit. The ith element in the array defines the ith segment in the segmented mask. ### x

X-axis values for the limit. ### y

Y-axis values described by formulas, such as -92.5+21.5 * log2 (x) where x is the x-axis value. You can enter only single-variable formulas. You also can enter constants, such as -95.0. ## dx

X-axis interval between input data points to compare against the limit. The node uses this input to interpolate the y-axis value for the limit.

Default: 1 ## x0

Starting x-axis value of the input data to compare against the limit. The limit is undefined for values of x that are smaller than the first element in x.

Default: 0 ## error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error  If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error ## limit

Segmented mask as defined by specification, dx, and x0. ### x0

Starting x-axis value of the limit. ### dx

X-axis interval between points in the limit. ### y

Y-axis values for the limit. ## error out

Error information.

The node produces this output according to standard error behavior.
