An LTID system frequency response over |omega| < or equal to pie is H(Omega) = rect (Omega / pie) * e^ -j*2*Omega, Omega being the symbol for big omega , absolute value of Omega < or equal to pie. Find the output y[n] of this system, if the input x[n] is given by:
A. sinc (pie*n / 2)
B. sinc (pie *n)
