E2.5. Construct the block diagram and signal flow graph of the discrete time systems whose input-output relations are described by the following difference equations. a) y(n) = 2y(n 1) +2.1x(n-1)+0.5 x(n-2). b) y(n)=1.6x(n-2) +0.7 x(n) + 3y(n-1) + 0.3 y(n-2). E2.7 Consider the following signal. afl Sketch and label: a) x? (t)= x(t-2) b) x?(t) = x(2t) c) x3 (t) = x(0.2t) d) x4(t) = x(-t)
