An LTI system S is cascaded in series with two other non-LTI systems as follows: x(t) w(t) S S: LTI z(t) S2 y(t) H(j?) The system S? is given by: And the system S? is: w(t) = x(t/2) y(t) = z(2t) The system S has H(j?) as its frequency response. (This question continues on the next page.) (a) Find how Y(j?) is related to X(j?), in terms of H(j?). Deduce the overall frequency response $H_{eq}(j?) = \frac{Y(j?)}{X(j?)}$. (b) If H(j?) is given by: $H(j?) = \frac{2a - j?}{2a + j?}$ where a > 0, find the impulse response h(t) of the system S. Deduce the overall impulse response $h_{eq}(t)$.

A Social Model for a Smartphone. You will need to sketch out the social model that could be used for you and your friends. So it will need to meet your requirements. Usage Scenarios for Your System. Goal: Get some practice in writing usage scenarios. Activities: Select one or two good representative task threads for the most interesting user class, for example, the customer. Write a couple of detailed usage scenarios, referring to user roles, tasks, actions, objects, and work context. Work quickly; you can clean it up as you go. Hints and cautions: Do not worry too much about the design yet; we will get to that. Deliverables: A few usage scenarios to share and discuss. Schedule: An hour should be enough time for this one.
