hi, after doing the FFT i got my fundmental component as (real = 1200 imag = -1300) and my second harmonic component as (real = -90 and imag = 60). Now i want to do squaring of individual component add the real and imaginary component and do the sqrting of the result in order to get the magnitude. but i am not able to do it in Frac16 as 90 and 60 are too small numbers for Frac arithmatics and i am getting zero as my result. Is there a third party sqrt function availble for 56f807evm? can anyone suggest a way of finding harmonics by any alternative way. Kedar |
Squaring , adding, sqrt ing small value ( Frac16 = 90)
