What is a Swept Sine signal and how it can be generated in ASI Datalab?

Swept Sine

A swept sine signal is a sinusoidal waveform whose frequency varies with time. Thus, the peaks in this signal will get closer together or further apart as time goes on. By applying a ‘sine swept’ to a system, we can measure the system’s response to sinusoids of various frequencies. System’s response to other inputs can be predicted using these measured responses.

To get swept sine waveform in ASI Datalab following parameters are required as Input:

  • Time Length(s) – The time period for which the signal should be generated
  • Start Frequency (Hz) – The initial frequency with which the signal has to be generated
  • End Frequency (Hz) – The frequency at the end of the signal
  • Sampling Rate(samples/sec) – How many samples should be generated in each second
  • Y unit – The Unit for the Y axis
  • Amplitude – Required maximum value of the signal
