Hi,
I'm wanting to measure AC voltages using the ADC on an AVR micro.
Should I rectify the voltages, then feed the DC voltage into the ADC, or is there a better way?
The calculation time has to be pretty quick, so I'm guessing it would be unreasonable to sample the AC voltage and calculate an average or something...
Thanks a lot,
Sam
