Hi, I'm trying to model the transmission loss and SNR of an acoustic signal underwater. I'm using this expression to modelize the transmitted signal:
y = sqrt(P)*exp(1i*2*fr*pi*t)'
where P is the transmission power in watts, fr is the transmission frequency and t is the acquisition time.
Calculate the insertion loss of the T-network given the values:
Rs = 75Ω
Rl = 100Ω
Ra = 13Ω
Rb = 13Ω
Rc = 213Ω
The transmission matrix and Network are below:
2. Homework Equations
The Attempt at a Solution
Constructing the matrix:
A = 1+Ra/Rc = 1+13/213 = 1.061
I have some problems to understand how to calculate the transmission loss at long distance, which model do I have to use?
I was looking into the energy flux model (Weston model), but I didn't understand at what range I should switch from "mode stripping" to "single mode".
I am working...
