Signal Generator

The Signal Generator tool generates common test signals like frequency sweeps, sine waves and Gaussian noise with different frequency distributions (referred to as "colors").

The Signal Generator can create a range of different test signals.

The generated signal is inserted into the clip at the cursor position. The duration of the generated signal is set by the Duration parameter.

Parameter Settings

• Signal type

  The signal type can be:

  • Sine: sine wave with constant frequency.
  • Exponential sweep: Sine wave with exponential transition of frequency from Start frequency to End frequency.
  • Linear sweep: Sine wave with linear transition of frequency from Start frequency to End frequency.
  • White noise: noise with Gaussian value distribution and a flat frequency distribution.
  • Pink noise: noise with Gaussian value distribution and a 1/f type frequency distribution
  • Brown noise: noise with Gaussian value distribution and a 1/f2 type frequency distribution.

• Duration (seconds)

  The duration of the test signal to generate specified in seconds.

• Amplitude (dB)

  The RMS (mathematical) amplitude of the signal to generate. Colored noise signals are defined at 1 kHz.

• Start Frequency (Hz)

  he start frequency of linear and exponential sweeps or the frequency if Signal type is Sine.

• End Frequency (Hz)

  The end frequency of linear and exponential sweeps.
