Waveform Types

Digilent® Analog Discovery™ devices support generation of arbitrary waveforms, standard waveforms, or both. If your device supports standard waveforms, you can set the gain, offset, and frequency to control the output. Standard waveform types include:

  • Sine

  • Square

  • Triangle

  • RampUp

  • RampDown

  • DC

You can control the behavior of different waveform types using the associated properties. This table shows you which properties work with the supported waveform types for Digilent devices.

This diagram illustrates how these properties affect a standard square waveform.

Square wave affected by changes in duty cycle, gain, offset, and phase

Standard waveforms cannot be clipped. You must keep gain and offset values so that the waveform amplitude remains within voltage range. You cannot change gain and offset of arbitrary waveforms.
