where T is the sampling interval. Is this system recursive or nonrecursive in nature?

Prob. 5.4-2

Consider the digital integrator in Prob. 5.1-1.

(a) Realize the system using gain, delay, and summing blocks. Apply δ[n] at the input of the realization, and find the resulting impulse response h[n] by inspection.

(b) Determine the unit impulse response h[n] by using the methods of Sec. 5.4.
