Question 1: State the differences between Analog and digital filters. Question 2: Sketch the following discrete time signal: a- y[n] = 0.58[n +1] + [n - 1] -0.58[n + 2] b- x[n] = 8[n+ 1] - u[n-1] w(n) = Ek+8(n + k) Question 3: Given the following linear systems. Determine if each is causal, linear and proof your response a) y(n) = 3x(n-1) + x(n-2) for n 20 1 b) y(n) = x(n) - 2 x(n + 1) TE c) w(n) = 2 x++x(n-1) 2
