Figure 14. Tone burst generator
For a tone burst generator the first timer is used as a monostable and determines the tone
duration when triggered by a positive pulse at pin 6. The second timer is enabled by the high
output or the monostable. It is connected as an astable and determines the frequency of the
tone.
