Generates a signal using a formula.
DC offset of the signal.
Default: 0
A Boolean that specifies whether to reset the timestamp of the output signal to zero.
True | Sets the timestamp of the output signal to t0 if t0 is available, and resets t in formula to zero. |
False | Does not set the timestamp of the output signal to t0 if t0 is available, and does not reset t in formula to zero. |
Default: False
Amplitude of the signal. The amplitude is also the peak voltage.
Default: 1
Frequency of the signal in Hz.
Default: 10
Representation used to generate the output signal.
The following table lists the defined variable names and their definitions.
f | Frequency variable equal to the frequency input |
a | Amplitude variable equal to the amplitude input |
w | 2 * pi * f |
n | Number of samples generated since the last time this node was reset |
t | Number of elapsed seconds |
fs | Sampling frequency variable equal to the sample rate input |
Default: sin(w*t)*sin(2*pi(1)*t)
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 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.
This input is available when you configure this node to return a waveform or an array of double-precision, floating-point numbers.
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.
Error information.
