Generates a signal containing a chirp pattern.
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.
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.

If the sequence Y represents chirp pattern, this node obtains the elements of Y using the following equation:
