This is my extra credit assignment so don't tell me answers, but please guide me how I should do this. I need to learn.

Question states: Determine the power output of the receiver in watts and in the appropriate measure of dB

let: Pin = 2W

diagram: --> [ G1 = 1/4 ] --> [ G2 = 1/10 ] --> [ G3 = 20 ] -->

How should I start?

After some thinking..

I'm not sure but G might represent the General formula which is G = Pout/Pin

EDIT

Is this correct?

Pin(dB) = 10log(2W/1W) = 3.01dB --- as input

dB = 10log(1/4) + 10log(1/10) + 10log(20) = -3.01dB --- As output

So the output at the destination is 0?

    What are G1, G2 and G3 and what are the numbers 1/4, 1/10 and 20 associated with them?2011-11-30

    I don't understand how you got 4. So you saying 2W x 1/4 should be output of my first block?2011-11-30
