  The idea is to get information, waveforms, circuit diagrams conventional electronic circuits, I also like to have a theoretical basis for implementing with microcontrollers.

    In the following video we can see some of the sounds I want to implement:

    Whelen Siren Sound

    I hope someone can help me.

This took 15 seconds on Google, only because I can't type very well:

You can also modify the code source given in this page to generate your own melody.

The author didn't copied well known siren sound but since you can modify the code source it isn't a problem

The site is in French but as far i know his work, the code source is in English

again dedending on what sound you want, Google is good at finding it.

If you need all the effects of a Whelen Siren Sound Unit, Google all the sound you need and start building.
