  1. Just to confirm my understanding, the DFT monitor takes phase shift into account. So if the reflected waves are out of phase, interference will affect the reading of the reflected power?
  2. Does waves with different frequencies interfere with one another? So for example, there are a 3000nm and a 5000nm wave. Does the two waves interfere or does fourier transform ignore the interference across waves with different frequencies?
