Jeri’s Short Circuit: A One-Bit ADC
YouTube player

We love Jeri Ellsworth’s electronics videos and have missed them of late (as she’s made the move from Oregon to Washington to work at Valve Software). She’s baaaaack! And with a cool, simple circuit for building a 1-bit analog-to-digital converter (ADC) using a single flipflop IC (such as a 74LS*) to do the sampling. If you’re still with me, you shouldn’t have any trouble understanding this tricky little circuit and why it’s cool.

    Where is the video ??????

    This is not PWM. It is Delta-Sigma Modulation (http://en.wikipedia.org/wiki/Delta-sigma_modulation).
