Signal generator: generates a variety of waveforms.
Supports an output of type complex, float, int, and short
Parameters
(R): Run-time adjustable
- Sample Rate (R)
- default: samp_rate
- Waveform (R)
- options: [Constant, Sine, Cosine, Square, Triangle, Saw Tooth]
- For selection with a variable, the following values should be used:
constant = 100 sine = 101 cosine = 102 square = 103 triangle = 104 sawtooth = 105
- Frequency (R)
- frequency of the waveform (default: 1000)
- Amplitude (R)
- amplitude of the output (default: 1)
- Offset (R)
- offset from zero (default: 0)
- Initial Phase (Radians) (R)
- default: 0
Messages
The 'freq' message port has been deprecated in 3.9 in favor of the 'cmd' message port.
The 'cmd' message port accepts message pairs.
- 'freq' . float value
- 'ampl' . float value
- 'phase' . float value
- 'offset' . float value
