The system S represented in the figure below is known to be time-invariant. When the input signals are x [n] and x [n], the outputs are y [n] and y [n]. Assume that the system is linear and b = 4. x [n] 4 [n] -2 -1 0 1 2 -4 2 n y [n] 4 -2 n -1 S Find the output signal y [n] for -2 n 2 when the input signal is x [n], shown in the figure below. 1,0 26 b 0 -2 -1 O 1 2 3 4 1 2 oe ByLEC Engineeting
