Atransmission channel is made up of three sections. the first section introduces a loss of 16db, the second an amplification (or gain) of 20db and the third a loss of 10db. assuming a transmitted power level of 400 mw, determine the mean output level of the channel.

Explanation:

The attached image shows the system expressed in the question.

We can define an expression for the system.

The equivalent equation for the system would be

so, the input signal could be expressed in dB terms

(1)

so the output signal could be expressed as.

The gain should be expressed in dB terms and power in dBm terms so

using the (1) equation to find it in terms of Watts

answer: strength i guess

explanation:

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
