Question 2
What is the Z-transform of the discrete-time unit impulse function, $\delta[n]$?
Question 3
A causal, linear time-invariant (LTI) discrete-time system is guaranteed to be Bounded-Input, Bounded-Output (BIBO) stable if what condition is met?
Question 4
A discrete-time system is described by the difference equation $y[n] = 0.5y[n-1] + x[n]$. What type of system is this?
Question 5
