What is AWG? & Why AWG?

→ AWG is an electronic instrument used to generate electronic Waveforms of desired shape.

These waveforms can be either single-shot or Repetitive.

How does it work?

Using DDS. . .1. Pick any time T for the ramp

function R(t).2. Calculate f(ξ) with the given

formula by chopping out the integer part.

3. Replace the Ramp value R(t) with the Arbitrary function value f(ξ).

4. Repeat for all other Time periods.
