Help! Full Wave Rectifier Bridge Network

[benboards]

Hello, I'm a student working on a microcontroller project. I have this 38 volt peak-to-peak AC wave i divided to 5 volts peak-to-peak. I want to send this signal through a full wave rectifier bridge network to establish a DC voltage i can use for my A/D converter.. Is there a way to to get the voltage out to be a steady state DC voltage rather than a pulsed voltage?? thnx!

You basically add capacitance on the output, to smooth the pulses. The value is fairly critical, as it must drop to follow changes in the signal. I would suggest you try looking for AC millivoltmeters, VU meters, and precision rectifiers.
