Greetings,
First i want to thank you for the Precision Rectifier Explained video, it was a really amazing explanation.
I have a question about the value of the resistors to set the gain for this circuit:
I need to set the gain of 50, so should i use 20k and 1M, or 2k and 100k?
Here some parameters:
- My signal will go from -100mV to 100mV at 4kHz max
- The opamp will have a single power supply of 0-24V (no way to have a dual power supply)
- The resistors are 1% rated
- I need to measure only the peak voltage of the signal
Best Regards
