If x(n)=A, -M<n<M,; x(n)=0, elsewhere. Then what is the Fourier transform of the signal?

( frac{sin u2061(M- frac{1}{2}) }{sin u2061( frac{ }{2})} )

A ( frac{sin u2061(M- frac{1}{2}) }{sin u2061( frac{ }{2})} )

A2 ( frac{sin u2061(M+ frac{1}{2}) }{sin u2061( frac{ }{2})} )

A ( frac{sin u2061(M+ frac{1}{2}) }{sin u2061( frac{ }{2})} )

( frac{sin u2061(M- frac{1}{2}) }{sin u2061( frac{ }{2})} )
