(a) Find the output c(kT) for the system of Fig. P4.3-6, for e(t) equal to a unit-step function.

(b) What is the effect on c(kT) of the sampler and data hold in the upper path? Why?

(c) Sketch the unit-step response c(t) of the system of Fig. P4.3-6. This sketch can be made without mathematically solving for C(s).

(d) Repeat part (c) for the case that the sampler and data hold in the upper path is removed.
