Question
![i) Suppose that three systems are connected in cascade. In other words, the output of
Sį is the input to S2, and the output of S2 is the input to S3. The three systems are
specified as follows:
S1 : yı[n] = x1[n] – x1[n – 1]
S2 : y2[n] = x2[n] + x2[n – 2]
S3 : y3[n] = x3[n – 1] + x3[n – 2]
-
Thus x1[n] = x[n], 12[n] = y1[n],
x3[n] = y2[n], and y[n] = ys[n]. We wish to
determine the equivalent system that is a single operation from the input ¤n] (into
S1) to the output y[n], which is the output of S3.
(a) Determine the impulse response h;[n] for each individual subsystem S;.
(b) Determine the impulse response h[n] of the overall system, i.e., find h[n]
