i need 2 types a full wave rectifier circuits. one without op-amp and one with an op-amp. My input is a 50hz sine wave.. can anyone of you all kindly post these 2 types of circuits. thank you.

thank you very much. But just a small clarification, for the circuit without the op-amp can i give ac input via the function generator or must i give through the transformer. and can i use LM741 for the op-amp ckt..

forget about transformer ..
just make sure that your function generator can drive the load that is connected to the bridge ..

by all means .. it's only 50Hz ..

Possibly the latter, if the signal generator has a common ground with the load. That's the problem of giving little more than no information with your question.

If you have a single ended source and intend a full wave-rectifier, some kind of signal inversion or isolation is needed. Other solutions exist for specific (or specified) applications.

Does this circuit gives a full wave sinewave? We have tried it out and it did not.

Can anyone kindly post or link a full wave bridge rectifier crocuit that does give a full wave sine wave. Thank you
