1. The problem statement, all variables and given/known data For each of the circuits, draw the waveform. The voltage drop across each diode is 0.7V 2. Relevant equations 3. The attempt at a solution I know that both of these are using diode bridges, but is there a specific name for these circuits? I think the waveform for Vo1 and Vo2 are rectified sine waves with peaks of 5.6 and -5.6, respectively. (at least that's what my notes say) I have no idea where to start with #2 though. Any hints/help would be greatly appreciated.
