In an attempt not to discourage you from future postings on sci.electronics.design or other newsgroups, I offer the following tips:
- Don't post your question in the message title. It's rude and will usually be ignored.
- Try to provide as much detail as possible in your question. Vague questions get vague answers.
- Be sure to use the correct terminology in your question.
- Mind your grammar.
To answer your question: information theory has almost nothing to do with amplifying a GPS signal. So I suspect you aren't using the terminology you intended to use. I assume you meant one of the following: A: How does information theory apply to a GPS signal? B: How do you amplify a GPS signal. If your question is A, I can offer very little. Information theory deals mainly with the limits and methods of communicating digital information. As far as I know, GPS is a digital transmission that is not especially limited by bandwidth or noise, accordingly, there is probably relatively little that information theory has to say about a GPS signal.
If your question is B, I offer the following information. Ask yourself why you are amplifying it? Then find a suitable amplifier to get from a
1.5GHz GPS signal to whatever output you desire.These are vague answers, but it was a vague question. Next time please be more specific or else people may not be willing to help out.
