Q1/ A narrowband FM signal has a carrier frequency of 90 kHz and a deviation ratio of 0.05. The modulation bandwidth (message signal bandwidth) is 15 kHz. This signal is used to generate a wideband FM signal with a deviation ratio of 22 and a carrier frequency of 120 MHz. I. Give the required value of frequency multiplication, n. II. Give two frequencies for the mixer to give the desired carrier. Define the required bandpass filter (centre frequency and bandwidth). II.

Assuming all terminals are rated 75°C and you have a #10 AWG THHN/THWN conductors in a conduit and the conduit is run on the roof off a office building where the ambient temperature never rises above 30°C the largest size circuit breaker or fuse permitted to protect these wires is:?
The wording that I am running into with questions such as "The number of conductors required to be installed between three-way and four-way switches is " is confusing. The text is not expalining this in a way that I am understanding anything other than grounding conductor, which is optional unless I am using a metal box. So what type of "conductor" is beng discussed?
Can I use a distribution box on every floor to distribute telephone lines to their designated outlets?
QUESTION 3 We are running 3 wires and a ground in a RMC to a control panel with a 60 amp circuit breaker disconnect in the control panel. The conduit is run along the ceiling where the ambient air temperature is 100 degrees. The control panel feeds our secondary cooling pump. What size are the ungrounded conductors? All conductors have typeTHHN insulation.
The only way to reach any of the levels where ABC Company is located in a building with ten stories is to use the elevator. In addition, those on the ninth and tenth levels need to connect to a group of servers located on the eighth. Describe the best wiring for the lift shaft. Pick the best option if there is more than one and justify your decision. If you think that interfloor connections may need to operate at substantially greater rates in the future, you may want to reconsider your current option. What is the optimum media for unbounded data transfer requirements? Justify your response.
