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...

Fourier Transformation Exam Questions and Answers Discrete Fourier Transform - Answer-All our data is digital and the FT works on analog. So we need a discrete formation of the FT Discrete Fourier Transform (DFT) - Answer-1)Assumes regularly spaced data values 2)Returns the value of the fourier transform for a set of values in frequency space which are equally spaced Matlab Functions - Answer-fft(X) fft2(X) fftn(X) Phase Spectrum = angle(fft(X,N)) Linear Operator - Answer-If f(X...
