Signal Source

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

Example Flowgraph

This flowgraph is for version 3.9+.
