Hi, I'm an undergrad (junior-to-be) EE student with a research project this summer and I was wondering if anyone could help me out.
I am trying to convert the frequency signal of my anemometer to a
voltage signal, but my frequency to voltage chip (LM2907) requires a +/-
15mV swing on either side of the inverting input. My input voltage is
currently 0-5v. I think I need a voltage level shift circuit(?) to shift my input voltage slightly negative. Can anyone help me out with that? Or recommend good webpages (or another name I could look up in my textbooks?)
Thanks Very Much!
