You are working for a long-distance telecommunitcation carrier. One of your technicians, on site at one of your transmission shacks on a microwave transmission system in Kansas, reports to you that they are experimenting a 12dB lose on the signal because of the winter storm conditions, which [since it is noise, and is working against our signal integrity] You hate to report on this decrease in service to management. How will you explain to your company's management team what the decrease in transmission capability the storm is causing?


If anyone could give me a good answer to this within 20 minutes I would greatly appreciate it.

12dB loss != noise...

Noise is an unwanted signal intefering with one you do want.

The storm is causing the recieved signal strength to be lower than it should be (which in turn means the amplifiers have to work harder to recover said signal resulting in more percieved noise).

if I remember my log scales correctly that 12dB means the signal is about 1/8th what it should be?
