Generates a signal containing a triangle wave.
DC offset of the signal.
Default: 0
A Boolean that determines the initial phase of the wave.
True | Sets the initial phase to phase in and sets the initial time to t0 if you configure this node to return a waveform. Sets the initial phase to phase in if you configure this node to return a double-precision, floating-point number or an array of double-precision, floating-point numbers. |
False | Uses the values of phase out and t0 from when the node last executed as the initial phase and time of the wave if you configure this node to return a waveform. Uses the values of phase out from when the node last executed as the initial phase of the wave if you configure this node to return a double-precision, floating-point number or an array of double-precision, floating-point numbers. |
Default: False
Amplitude of the signal.
Default: 1
Frequency of the signal.
Default: 10
Initial phase in degrees of the signal when reset phase is True.
Default: 0
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
Sample 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.
Phase, in degrees, of the next sample of the output signal.
Error information.
The node produces this output according to standard error behavior.

If sequence Y represents a triangle wave, this node generates the pattern according to the following equation.
for i= 0, 1, 2, ...,n-1
where n is the number of samples. The node calculates tri(phase[ ]) according to the following table.
pmod[i] | tri(phase[i]) |
---|---|
where pmod[i] is phase[i] modulo 360 and phase[i] is:
where initial phase is the initial phase of the wave.
