In x(n) 12 H₁(z) x(n) ↓2 the input signal is upsampled by I = 2, then filtered by H₁(2), and then downsampled by D = 2. Provide an argument that shows whether or not it is possible to find H₂(z) in H₂(z) y(n) y(n) so that the two systems are equivalent. If you argue that it is possible to find such an H₂(2), express this H₂(z) in terms of H₁(z).
