I need help in designing a tone generator that sweeps at a frequency of 100Hz to 3kHz in a span of two seconds. It is powered by a 12 volts source and is enabled by an external trigger. The external trigger enables the tone generation when is at least 6 volts; otherwise no tone is generated. An 8-ohm speaker is used to produce the sound.
So far this is what I am able to come up with.

There is already external trigger.
The only problem left is the frequency sweep of 100Hz to 3kHz in a span of 2 seconds.
Thank you in advance.
