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.

polarized antenna whose reception characteristics near the main lobe are given approx-
imately by

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.

An ideal low pass filter is used at the receiver input to reduce the noise as much as possible, while transmitting the desired signal. (a) By what factor should the cutoff frequency of the noise reduction filter be reduced in the 16-PAM case, compared to binary? (b) By what factor will the noise power at the decision circuit be reduced in the 16-PAM case? (c) By what factor will the noise amplitude at the decision circuit be reduced in the 16-PAM case?

P.6.7-5 Data at a bit rate Rb must be transmitted using either binary NRZ polar signaling or 16-ary PAM NRZ polar signaling. (a) By what factor will the symbol rate be reduced in the 16-PAM case? (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.
