Consider the discrete-time system below with input x[n] and output y[n]. In the figure, h₁[n] and h₂[n] denote the impulse responses of LTI Subsystems 1 and 2, respectively. Also, δ[n] is the unit impulse, and b > 0. Assuming h₂[n] ≠ δ[n], the overall system (denoted by the dashed box) is _________.
