# Scaling and Mapping (Linear Scale) (G Dataflow)

Scales a signal based on a straight line.

## signal

Input signal.

This input accepts the following data types:

• Waveform
• 1D array of waveforms
• Double-precision, floating-point number
• 1D array of double-precision, floating-point numbers
• 2D array of double-precision, floating-point numbers
• 1D array of complex double-precision, floating-point numbers
• 2D array of complex double-precision, floating-point numbers

## scale

Slope used for linear scaling.

The following equation defines linear scaling: $y=mx+b$, where m is scale.

Default: 1

## offset

Intercept used for linear scaling.

The following equation defines linear scaling: $y=mx+b$, where b is offset.

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

## scaled signal

Result of scaling the input signal.

This output can return the following data types:

• Waveform
• 1D array of waveforms
• Double-precision, floating-point number
• 1D array of double-precision, floating-point numbers
• 2D array of double-precision, floating-point numbers
• 1D array of complex double-precision, floating-point numbers
• 2D array of complex double-precision, floating-point numbers

## error out

Error information.

The node produces this output according to standard error behavior.

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.

Where This Node Can Run:

Desktop OS: Windows

FPGA: DAQExpress does not support FPGA devices

Web Server: Not supported in VIs that run in a web application
