AM radio -- please help!
Hello,
Here is some background info. I don't know if it is all necessary to find a solution but here it is anyway:
I am currently living in State College, PA. I would like to be able to listen to an AM radio station broadcasting from Philadelphia, PA...
From physics sheet - "all signals (digital a reduction in signal power) as they travel through a system and need amplification at certain intervals." Why is this the case?
I am currently studying an International Baccalaureate Physics course, and I am currently in my first year of study (i.e. I'm 16). As part of this, I am doing a presentation on cellphones; not my decision, but to get to the point:
If anyone could refer me to some information detailing which...

This is a pretty basic concept of relativity that used to make sense to me but I have since become a little unclear on the issue.
The question is how can one violate the principle of causality simply by broadcasting information that travels faster-than-light?
it has always seemed incredible to me how little power it
takes to transmit radio signals over vast distances,i have
read about how these signals are self sustaining, i was
wondering how long a signal could retain its information,
could it go clear across the galaxy?
SETI's search for alien contact includes detecting intelligent analog transmissions and also those carrying sequences of prime numbers signifying life elsewhere in the Galaxy.
What is the relative ease with which SETI can discern rational analog vs prime number transmissions? Is it a waste...
