Hi all,
I'm trying to to find the ratio of two sinus shaped signals in the same phase.
From the two AC signals I want a DC voltage representing the amplitude ratio of the AC signals.
First thought is to use an opamp with a variable gain (one of the two signals) but i'm getting a bit stuck on how to actually do this.
Can anyone hint me towards a solution?
Thanks,
