Fourier Transform Test 1 Questions with Correct Answers Why doesn't the normalisation vectors apply to the DC-component (values at t=0)? - Answer-Because the DC component don't have a negative counterpart. It's the average value of all data points. How does amplitude in time and frequency domain differ? - Answer-The amplitude is the length of the complex vector in frequency, hence it cannot be negative. Amplitude in time-domain, however, indicates direction in addition to magnitude and...
