hello frnds...
i want to measure harmonics but i have no knowledge about it so please help me about it...
please give me tutorial or details about harmonics...

@ jigneshdoshi
normally harmonics leads to DSP (Digital Image Processing)
for finding harmonics u need FFT (Fast Fourier Transform)
now using Matlab it is easy as that is a big tool
using too much memory behind it but using controller that has limited memory
u need to do some tricks
u need to find out coefficients of transforms using matlab and use that in ur code
obviously no fractional used whole words
also u has to know the logic behind FFT
also decided how much points of FFT transform u has to done using controller
