Homework Equations
The Attempt at a Solution
I'm having trouble getting start with this one, but here's what I've got so far.
I assumed R is the signal received by the TDS.
[tex]P(R=X) = \mu \quad , \quad P(R=N) = 1 - \mu[/tex]
Now in part (a) I believe we are looking for,
[tex]P( X \geq \gamma A | R = X)[/tex]
The only other thing I can think of applying is Bayes rule,
[tex]P( X \geq \gamma A | R = X) = \frac{P(X \geq \gamma \cap R = X)}{P(R=X)}[/tex]
Also I think I have to incorporate the probability density function into the problem as well and I haven't done so yet.
Any ideas/suggestions?
Thanks again!
