1. (10 pts) A mobile receiver communicates with
the transmitter at an operating frequency of 550 MHz at a distance
of 3 km. Calculate the path loss in the system.
2. (15 pts) Assume that two antennas are
half-wave dipoles and each has a gain of 3 dB. If the transmitted
power is 1 W and the two antennas are separated by a distance of 10
km, what is the received power? Assume that the frequency is 100
MHz.

A doppler meter of frequency 3 MHz (accurate to +/ - 10
Hz) is used to monitor the heart rate of a fetus in early pregnancy
(8 – 10 weeks). Determine the maximum positive and negative shift
in ultrasound frequency detected by the meter due to the heart
motion. For a simplified model, take the main fetal heart muscle to
move like a mass on a spring undergoing Simple Harmonic Motion,
with a maximum distance (amplitude) x max = A...
