If we calculate Total harmonic distortion(THD), we need to obtain the spectrum data which has 2nd,3rd,4th, n th harmonic data. I am wondering how many nth harmonic data we need to include to obtain THD value(% or dB).
Original signal from function generator is 100MHz 0.2V and I obtained 5th harmonic in the oscilloscope. 5th harmonic one is around -50dB(amplitude).
