Brief: Generates signal waveform following any of a set of common periodic functions.

Input - Accepts several input types (integer, string, tuple, array)

Properties:

  • Amplitude(double) - the amplitude of the signal waveform in either direction from zero, e.g. a value of 1 produces a waveform in range [-1,1]
  • BufferLength (int) - the number of samples in each output buffer
  • Depth (System.Nullable<OpenCV.Net.Depth>) - target bit depth of individual buffer elements (optional, choose from U8, S8, U16, S16, S32, F32, F64)
  • Frequency (double) - frequency of the signal waveform in Hz
  • Offset (double) - DC offset of the signal waveform (optional)
  • Phase (double) - phase offset of the signal waveform in radians (optional)
  • SampleRate (int) - the number of samples generated in Hz
  • Waveform (Bonsai.Dsp.FunctionWaveform) - the periodic waveform used to sample the signal, choose from Sine, Square, Triangular, Sawtooth

Output (OpenCV.Net.Mat) - a 1 x N array where N is BufferLength

tip

To limit the waveform to positive values, use equal values for Amplitude and Offset

tip

To produce a rectangular waveform with variable duty cycles, use Sawtooth waveform type, followed by a Threshold (Dsp) node
