P1.. Consider the two signals transmitted over an AWGN channel with zero mean and PSD 10-2 W/Hz. s₁(t) = u(t)-u(t-1)-[u(t-1)-u(t-2)] $2(t)=-[u(t)u(t-1)]+u(t−1)-u(t−2) a) Sketch the signal constellation b) Construct an optimum correlation-type demodulator for this system c) Determine the bit error probability Pb when P(S1)=0.4 and p(S2)=0.6

Orders for a computer are summarized by the optional features that are requested. The proportion of orders with no optional features is 0.24. The proportion of orders with one optional feature is 0.38. The proportion of orders with more than one optional feature is 0.38. (a) What is the probability that an order requests at least one optional feature? Round your answer to two decimal places (e.g. 0.98). (b) What is the probability that an order does not request more than one optional feature? Round your answers to two decimal places (e.g. 0.98). (a) i (b) i
