A discrete-time (DT) system S is described by Check the appropriate box indicating whether or not the system S sat- isfies the specified property. Justify your answers. True False 00 n+1 y[n] = [ (x[k])². k=n-1 Invertible Causal Stable

Using the discrete-time signals y₁ [n] and y₂[n] where: y1 [n] [-1 0 1 3 - 1 3 -1] and y2[n] = [-2 -1 0 - 3 2 1] Represent each of the following signals by a graph and by a sequence of numbers. a. x1[n] = [y2[n] - y1[n] b. x2[n] = y1[n] * y2[n], c. x3[n] = y2[1 - n] d. x4[n] = y1[n - 3]

i) Construct a 4-to-1 Multiplexer and provide a picture or snapshot of the circuit here. ii) Use the multiplexer you have constructed in part i)to implement this circuit: F(A,B,C) =  ∑m(0,3,4,7) Provide a truth table and a picture or snapshot of the circuit here.
