Thanks for the input. I'm not sure what the input resistance would be or what type of amplifier to use. The signal I need to amplify is limited to a RL of 1kohm.Can I rectify the output from the amp to get the signal to a DC level?
I would like to condition a signal generated by a laser that profiles the product we run. The output is a +/- 5vdc but the type of profile the laser generates actually produces a 50 - 200mv ac signal @ around 850Hz. I would like to look at only the ac signal and produce a 0-10 vdc output. The ac...
