Hello, i need to find in time serie, k=1,2,3...(how if possible) most domain
frequencies and than smooth original serie by Fourier row  y=mean +
a1*Cos(2*pi/freq*t)+b1*Sin(2*pi/freq*t)+a2......

numbers a1,b1 ... i will have from simple regresion, i need only to find k
msot domain frequensies a than i will have a1,b1,....ak,bk - coeficients.

Many many thanks for help.
