For fill factor=1/2 , periodic rectangular signal,i have to calculate Ak/A1 (db), Ak is the harmonic of order k of the signal.
Ak/A1=1/k when k is odd and 0 when k us even ,And i have the following formula in my textbook:
Ak/A1(db)=20lg(Ak/A1)=nk-n1=nk because n1=0 but what is nk when Ak/A1=0???We also set n1=0 from spectrum analyzer when we measured the signal.
Im very confused about this.
