Compare QAM and ASK in terms of its error performance and data rate. (4Marks) b. binary data is transmitted over a channel at a rate of f0 bits/sec. To reduce the transmission bandwidth, it is decided to transmit this data using 16-ary symbol. By what factor is the bandwidth reduced? (2Marks) What will be the increase in the transmitted power when the separation between pulse amplitude is same in both cases. Calculate the difference in maximum power level between ASK...

3. (40 points) A binary communication system transmits signals s (0) (i = 1, 2). The receiver samples the received signal r(t) = s(t)+ n(t) at T and obtain the decision statistic r =r(T) = S(T) + n(T) = a, un, where the signal component is either a = + A or a, = -A with A >0 and n is the noise component. Assume that s (6) and s(l) are equally likely to be transmitted and the decision threshold...

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
