| - | 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.

| 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.
