I need to turn a 60 Hz sinewave that has an offset of 2.5V into a lineal signal depending on the sinewave's amplitude. The sinewave's maximum peak-to-peak is 4V. That is, it has an amplitude of 2V, its lowest point will be at 0.5V and its highest at 4.5V. What I want to do is convert the signal produced by an AC current transducer to a linear output.
If the sinewave has a 0V amplitude (that is, it's a fixed 2.5V signal) the circuit's output has to be 0V. If the sinewave has a 2V amplitude, the circuit's output needs to be 5V. Something like the following graphs:
Any advice as to what technique would be best to approach this problem, maintaining simplicity and minimizing the number of components?
