Practice Problem on Discrete-time Fourier transform computation
Compute the discrete-time Fourier transform of the following signal:
$ x[n]= \sin \left( \frac{2 \pi }{100} n \right) $
(Write enough intermediate steps to fully justify your answer.)

Answer 1
$ x[n]=sin(2pi/100*n) $
$ x[n] = 1/(2*j)*(exp(j*2*pi/100*n)-exp(-j*2*pi/100*n)) $
$ X_( $
