Function Generator

Posted on Feb 6, 2014

The design includes a buffered virtual ground circuit provided by an LM741, LM318 or similar Op Amp, which sets a fixed voltage half way between the input voltage and ground. This is then used as the virtual ground for the sine and triangle wave outputs from the `WAVE_OUT` connector, providing an output centred around 0V. The amplitude and frequen
