1. I have some problems to understand this question see if there anyone who can help me:

The question is T7A16 on the Element 2 test:

decibel (dB) increase does that represent?

A) 2 dB

B) 3 dB

C) 5 dB

D) 10 dB

2. B. 3 dB

How can you get 3?

Don&#39;t tell me that you went to ARRL.org to look for the answer lolz

Can you tell me how can you get 3?

4. i remember i did this in physics last year...

if i can be bothered to look out my notes, i might scan them in

truth be told though, it&#39;s a bugger of an equation from memory

But i dont wanna just get the answer

I really wanna know why....

6. Can&#39;t recall, we don&#39;t use watts at all except for power consumption. All carried signal is measured in dB in cable.
