Signal generator, generates a variety of signals.

Supports an output of type complex, float, int, and short

## Parameters[edit]

**( 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
