FIG. 8.97 Generated waveform.

Fig. 8.97 shows the generated staircase waveform. In this figure, the vertical voltage axis is
1V/division, and the horizontal time axis is 100ms/division.

8.29 PROJECT 24—SAWTOOTH WAVEFORM

8.29.1 Description

In this project, we generate a sawtooth waveform with 10 steps with a period of 20ms, that
is, the time delay between each step is 2ms.

8.29.2 Aim

The aim of this project is to show how a sawtooth waveform can be generated.

8.29.3 Circuit Diagram

In this project, analog input PA_4 is used as in the previous project.
