Pattern Generator (Chirp) (G Dataflow)

Amplitude of the pattern.

Default: 1

Beginning frequency of the pattern in normalized units of cycles/sample.

Default: 0

Ending frequency of the pattern in normalized units of cycles/sample.

Default: 0.5

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

Sampling interval.

Default: 0.1

Number of samples in the pattern.

samples must be greater than 0. Otherwise, this node returns an error.

Default: 128

Timestamp of the output signal. If this input is unwired, this node uses the current time as the timestamp of the output signal.

This input is available only if you configure this node to return a waveform.

Output chirp pattern. The output pattern contains frequency ramping from f1 * f _s to f2 * f _s , where f _s is the sampling rate.

This output can return a waveform or an array of double-precision, floating-point numbers.

Error information.

The node produces this output according to standard error behavior.
