Circuit Simulator - Sawtooth Wave Generator

What is the application of sawtooth?

@Author.

I tried this circuit. Its not producing waveform. I tried with different values.

I tried the same circuit in multisim but the output is not coming may I know the reason?

How saw tooth wave works?

The sawtooth waves only real use is for sound synthesis. Hook the output up to an 8 ohm speaker and connect the speaker to ground to hear a pure unfiltered sawtooth wave.

I don't get it. It only starts oscillating after you disconnect the power. I need constant power. Well I guess its because nothing is drawing current to theres no where for the electricity in the wires to go.

What are the applications of the saw-tooth generator?

Thanks for the diagram. I drew up the circuit in Orcad Capture and was able to run it fine. I changed the capacitor to a smaller value to increase the frequency. I am trying to design a circuit that produces a sawtooth at about 110-120 Hz to mimic the fundamental frequency of a male speaker.
I used Capture to generate a Fourier transform of the signal, and thought that the energy drops off pretty quick for what I want. I'm messing with different component values to try to decrease the dropoff.
I changed the 5k for a 2k, and the upper 40k for 80k, resulting in an even steeper slope in the fast component of the waveform. The Fourier transform resulted in an even bigger drop between the fundamental and the second harmonic, but the amplitude at higher frequencies seems to persist.

I do not have waveform in the output! Why?

No voltage source input why?
