(c) Another LTID system, y2[n] is given by the following difference equation: y2[n] = x[n] + x[n – 1] + x[n – 2] + x[n – 3] (i) What is the impulse response of y2[n]? [C3, SP1] (ii) Let the system yi[n] and y2[n] are interconnected in such a way that the ouput of yı[n] becomes the input of y2[n]. Sketch a simple diagram that describe the interconnection of the two systems. [C3, SP1] (iii) From the system explained in (c)(ii), what are the magnitude of samples found in the output of y2[n] for 0 sn s 4? Suggest the expression of the output and plot its sequence.
