-An other voltage controlled oscillator. It comes with a really beautifull shaped sinewave - stabel and with the same peak to peak over all frequencies. One can switch between square, triangle and sine wave. In the square/​triangle mode one can change with a potentiometer from triangle to saw or the duty cycle of the square wave. In sine wave mode one can shape the sine wave to an interesting "sea saw" wave.\\+An other voltage controlled oscillator.

In the square/​triangle mode one can change with a potentiometer from triangle to sawtooth wave or change ​the duty cycle of the square wave.

 All OpAmps are the rail to rail [[http://​ww1.microchip.com/​downloads/​en/​DeviceDoc/​21733j.pdf|MCP6002]] ICs. For a perfect sine wave one should trim the 500R trim potentimeter to a symetrically wave.\\ All OpAmps are the rail to rail [[http://​ww1.microchip.com/​downloads/​en/​DeviceDoc/​21733j.pdf|MCP6002]] ICs.
