Hi Dave, thank you for your fast feedback. I gave a look in the meanwile: the data showed you is already my raw output from our bench (as raw as I have access to). I just placed it in a simple Excel scatterplot and magnified to see those bands clearly.Could it be that there's a similar...

Hello Gentlemen, I'm not an EE engineer, yet trying to help my colleagues. I would like to get a general feeling of what could be going on. Probably trivial for some of you. Background We have a motor/torque sensor device that is measuring torque values. We get out digital signals for Torque...

Hello Gentlemen, the schematic you proposed works (and it's simpler, as you pointed out). Thank you very much for the suggestion! I take the liberty to ask for some help more: Now the system works, but only if I connect the V- power line with Ground. I am using a typical "regulated DC power...

Interesting. You mean I should have a path to the Ground placing a MOhm resistor? Should i put between points A and D?

@jim hardy Thanks for your help Jim! This is great, but still I have some doubt: my system was giving a 2V constant voltage. It was completely independent on the amount of light the diode was receiving. There must be some other mistake.

Hello guys, thanks both of you for your answers! Let's reply with order: @BiGyElLoWhAt - I'm using an adjustable power supply unit, set to 5V. - I'm testing the photodiode just by intermittently illuminating it with a flashlight. By hand. The diode alone, plugged straight into an o-scope (or...

Dear electrical engineers, Here a question from a serious electronics n00b =D. I tried to build a system as shown in the image. I have a photodiode which gives me a clock signal in the range of 200 to 500mV. Frequency will be in the range of 100 to 1000 Hz. I would like to amplify this...
