hi everone
pls tell me how to measure the ripple voltage on battery input during the charging period. my pic controller is 10bit adc . the ripple voltage may be in between 100mv to 200mv. (ie. 0.1v) i tried to measure the ripple voltage using voltage divider but the problem is i couldnt get accuracy. wht i missed in this measurement method. suggest some method or ic for accurate reading
