Hi All
I am new here, so be gentle
I am currently struggling with what should be a simple analog problem:
Need to convert a square wave signal to a 0v based square wave.
I.E. The signal has an amplitude of 0.5v, but a varying offset from about 11.5v to about 13v.
How do I reject the offset?
I have tried to use a DC block with a cap but end up getting a negative voltage component which is not desirable (the entire circuit is single supply).
Also tried many other solutions to no avail, including using a high voltage instrumentation amp (INA126).
As you may be able to tell, my skills are digital, not analog!
