Consider a causal continuous-time system with impulse response h_c(t) and system function?

(a) Use impulse invariance to determine H₁(z) for a discrete-time system such that h₁[n] = h_c(n T).

(b) Use step invariance to determine H₂(z) for a discrete-time system such that s₂[n] = s_c(n T), where

(c) Determine the step response s₁[n] of system 1 and the impulse response h₂[n] of system 2. Is it true that h₂[n] = h₁[n] = h_c(n T)? Is it true that s₁[n] = s₂[n] = s_c(n T)?
