- Hello to all of you; wow, 3 comments this year on a 17 year old idea. I am the original author, and searched this to use the illustration as an example of what NOT to do. You are all correct, the labels are indeed wrong. Good catch. I do not recall anyone actually using this circuit of which I knew. It was based on me measuring IB vs IVR and noticing a zero crossing. Perhaps this is only a stupid pet trick, but I'm OK with that.
