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.

(b) By what factor will bandwidth required from the (lowpass) channel be reduced 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.
