Question

Hello, Experts!

Tomorrow i have a final examination (digital signal processing), so please giving me a hand to solve this question as soon as possible.

Here is my question. Thank you pretty much!!!

Question 2: (25 marks) Given two systems with the unit impulse responses are connected in cascade (2)-u-n] 4 n-1 11 1 n-1) 7 7 h2n] = 6n]-3"-1ul-n 4 Find the Z-transform for each individual systems and the cascaded system? b. Determine the Causality, Stability, ROC for each of individual systems and the cascaded system? Sketch the frequency response of the cascaded system? d. Realize the block diagram or the signal flowehart for the cascaded system using the cascade form? a. C.
