Dear Sir, I had a small query which i thought i would ask you. can you please tell me if there are IC's which can read and measure AC signal, convert it to DC,trace the 2nd and the 5th harmonic component in an AC wave of fundamental frequency of 50Hz. if yes can they be interfaced with a microcntroller. If not then please tell me if there are any alternatives.I also want to know more about True RMS IC's. So waiting for your reply.

Thanking You

Regards Pavan

50 Hz is slow. How about running your signal into a D/A and computing what you want in the microcontroller?

What you are searching is a spectrum analyzer in a simple form. Google for Fourier Analyses. In your case I thin a simple FFT would do.
