How to trigger this input ?
Hello !!
Happy new years every body !
I have a signal coming from a coil and the best I have found to have it is imply to amplify it with a INA128 (white curve). Almost nos noise and even at 1 meter I have more than 1 volt.
Now I would like to input that signal to a PIC. I try to use a diode to eliminate the negative part of the signal (a 1N4148), but I did not obtaine what expected (green curve).
What I am doing wrong ?
I have a second question : is it possible to use this signal (+/-5 Volts) with a CI like 74HC132 to have a nice digital signal ?
Thanks you for your help,
Jean-Marie
