The cost of computing the Fourier coefficients is ___________ (Note: ‘N’ is the number of grid points).

The cost of computing the Fourier coefficients is ___________ (Note: ‘N’ is the number of grid points). Correct Answer N2

The computational cost required for computing Fourier coefficients, if done in the most obvious manner, is N2. This is prohibitively expensive. It is twice that of the backward substitution for Gauss-Elimination method.

Let x(t) be a periodic function with period T = 10. The Fourier series coefficients for this series are denoted by $${a_k}$$ , that is
$$x\left( t \right) = \sum\limits_{k = - \infty }^\infty {{a_k}{e^{jk{{2\pi } \over T}t}}} .$$
The same function x(t) can also be considered as a periodic function with period T' = 40. Let bk be the Fourier series coefficients when period is taken as T'. If $$\sum\limits_{k = - \infty }^\infty {\left| {{a_k}} \right|} = 16,$$    then $$\sum\limits_{k = - \infty }^\infty {\left| {{b_k}} \right|} $$  is equal to

Computing the Fourier transform of the Laplacian result in spatial domain is equivalent to multiplying the F(u, v), Fourier transformed function of f(x, y) an input image of size M*N, and H(u, v), the filter used for implementing Laplacian in frequency domain. This dual relationship is expressed as Fourier transform pair notation given by_____________ F(u,v) b) ∇2 f(x,y)↔-F(u,v) c) ∇2 f(x,y)↔-F(u,v) d) ∇2 f(x,y)↔F(u,v)

X sues A and B on a promissory note executed by A, B is A's nephew, and he is joined as a defendant on the ground that A and B are member of a joint Hindu family, and that the note was for a debt binding on the family. None of the defendant appears at the hearing and an ex parte decree is passed against both the defendants.
The decree against A proceeds on the ground that the note was passed by him and against B on the ground that the debt was incurred for a family purpose. B applies for an order to set aside the decree, alleging that the summons was not served upon him and that the debt in respect of which the note was passed by A was not incurred for a family purpose. It is not disputed that the amount was actually advanced to A.
