Generates a waveform containing a triangle wave.

Details  

	offset is the DC offset of the signal. The default is 0.0.
	frequency is the frequency of the waveform in units of hertz. The default is 62.5.
	amplitude is the amplitude of the waveform. The default is 1.0.
	phase is the initial phase, in degrees, of the waveform. The default is 0.0.
	#s is the number of samples in the waveform. The default is 128.
	Fs is the sampling rate in samples per second. The default is 8000.
	signal out is the generated waveform.

EMB Triangle Waveform Details

If the sequence Y represents Triangle Waveform, this VI generates the pattern according to the following equation.

y[i] = amp × tri(phase[i]), for i = 0, 1, 2, …, n – 1,

where amp = amplitude, n = number of samples (#s), and tri(phase[i]) is:

(2 × pmod/180.0) if 0 pmod < 90.0

or

(2 × (1 – pmod/180.0)) if 90.0 pmod < 270.0

or

(2 × (pmod/180.0 – 2.0)) if 270.0 pmod < 360.0

where pmod = p modulo 360.0 and phase[i] is:

initial_phase + frequency × 360.0 × i/Fs
