Fourier series Test Questions with Answers Name given to finite Fourier series - Answer-A trigonometric polynomial What is related to the decay of Fourier coefficients and how? - Answer-Differentiability of the function Higher differentiability higher the rate of decay Exponential decay if infinitely differentiable 3 ways to define a Fourier series for a function f(x) on domain 0 ≤ x ≤ c - Answer-1) Translate both directions by c to get a function where 2L = P = c and use the ful...

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...
