Problem 1: Two-Force Equilibrium
A 12 kg traffic light is suspended by two cables
attached to a ceiling. Determine the force in Cable 1
(AB) and Cable 2 (AC). In other words, determine the
tension in each cable, assuming the system is in static
equilibrium.

A circularly polarized wave, traveling in the +z-direction, is received by an elliptically
polarized antenna whose reception characteristics near the main lobe are given approx-
imately by

is
(a) right-hand (CW)
(b) left-hand (CCW)
An elliptically polarized wave traveling in the negative z-direction is received by a circularly polarized
antenna. The vector describing the polarization of the incident wave is given by Ei= 2ax + jay .Find the
polarization loss factor PLF (dimensionless and in dB) when the wave that would be transmitted by the
antenna is (a) right-hand CP (b) left-hand CP.

(b) By what factor will bandwidth required from the (lowpass) channel be reduced in the 16-PAM case? (c) Assuming the minimum spacing between pulse levels must be the same in both cases, by what factor will the average power be increased in the 16-PAM case? [Hint: take the pulse amplitudes to be ±A in the binary case, and ±A, ±3A, ±5A,..., ±154, and recall that scaling pulse amplitude by a factor k scales the pulse energy by a factor R². Assume that the data is random, so that all 16 levels are equally likely, and that the same pulse shape is used in both cases.] Warning: Solutions to the textbook problem that are posted online are mostly wrong.
