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?
