Tones and Noise (Frequency Domain » Evenly Spaced Tones) (G Dataflow)

A Boolean that specifies whether to coerce the tone frequencies.

Default: False

Value that the sum of all the tones is scaled to and the largest absolute value that the waveform contains.

Default: -1

A Boolean that specifies whether to reset the phase to the initial phase value and the timestamp to 0.

Default: False

An array in which each element is a single tone amplitude.

The size of this array determines how many tones are generated.

Start frequency and delta frequency of the tone.

start frequency

Lowest tone frequency generated.

This value must be an integer multiple of sample rate/samples.

Default: 10

delta frequency

Magnitude of the spacing between adjacent tone frequencies.

delta frequency must be an integer multiple of sample rate/samples.

If start frequency is 100 Hz, delta frequency is 10 Hz, and the tone amplitudes array contains three elements, the tone frequencies generated are 100 Hz, 110 Hz, and 120 Hz.

Default: 100

Distribution of the phases of the sine tones. The phase distribution affects the Peak/RMS ratio of the overall waveform.

Default: random

Causes reseeding of the noise sample generator when the value is greater than 0.

This node ignores seed if phase relationship is Linear.

Default: -1

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 rate in samples per second.

Default: 1000

Number of samples in the signal.

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

Default: 1000

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.

Generated signal.

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

Ratio of the Peak voltage to the RMS voltage of the output signal.

Tone frequencies generated after accounting for coercion and the Nyquist criteria.

Error information.

The node produces this output according to standard error behavior.
