n-1 The input to an LTI system is x n = u [n]and the corresponding output is y [n] = ()"*u [n+ 1]. Which of the following statement(s) are correct? O The system is causal O The pole-zero plot of H (z)is as follows: 0.8 0.6 0.4 0.2 -0.2 -0.4 -0.6 -0.8 -1 -1 -0.5 0.5 1 Real Part O The system is stable since the ROC of H (z) includes the unit circle. O The impulse response of the system is h (n] = 48 [n + 1] – 2(-)"u [n] O The z-transform of y n]is Y (z) = ROC < |z| < o0 4z Imaginary Part

For Digital Signal Processing: The following two signals are input to an analog to digital converter.  x1(t)=3.42cos⁡(5t) x2(t)=1.69cos⁡(10t) Consider an A/D converter having 5-bits and a full-scale amplitude range of 19. Let x1[n] denote the digital signal converted from x1(t) and x2[n] denote the digital signal converted from x2(t). Which digital signal will contain less quantization noise?
