I needed a signal generator that had a small footprint and a high sample rate; So I made one!
* Uses "duty dac"
* 600 kHz sample rate
* 4 waveform types (Saw, Triangle, Square, Noise)
* High resolution pulse width
* Outputs both normal and inverted signal at the same time
* Signal can be damped in steps of 6 dB
* All parameters can be changed on the fly
