I hate it when you get a teacher who comes up with crap not in the book and barely spend anytime explaining it. Here is one of those examples:

Quote

If a satellite is in geosynchronous orbit transmitting 10 watts with a transmit gain of 20 dB , what will be the received power at the earth station if the earth station receive antenna gain is 30B and the frequency is 2Ghz. The only loss you need to consider is free space loss. Show your calculations.

I'm not looking for an answer here. More or less just venting my frustration. But if you do know how to answer this PM me.

Does anyone else get bullsh*t like this, without being told how it works??

[Martyr2]

But you know, when you find the answer you are most likely not going to forget it! Sometimes it is nice to stick with the book but I have learned a hell of a lot in stuff that is not covered in a book.

There are advantages and disadvantages to this.

I am second with Martyr2. Yap, there are advantages and disadvantages to this. Sometimes we find answers not in the book, like new discoveries.

When Pythagoras discovered his "theorem on triangle" he did not refer the book, but did write it.

[Xenon]

if everyone was some newton,pythagoras etc i think the world would have been far more "advanced"(relatively).

i don't think most people can(not me if its maths) solve numericals just like that without any explanation. then what the hell are lecturers for?good explanation not only clears doubts but also generates interest in the topic(which is by far the most important thing)

now see if the lecturer explained the new topic, you might get interested in it rather than to complete it(it feels like a burden) and look out for information not in the book. it is much easier to learn when interested rather when burdened..

It's good to learn stuff out of the book yes. But Pothager-gimmie new the basics of math, or the rules needed, to make his thesis or whatever you want to call it. It sounds to me like Israel is mad because the teacher did not explain the rules needed. Maybe I am just rambling on.

Branching out is a good way of expanding your knowledge

[Israel]

Jesus Christ I finally found the answer:

Quote

From what I read on Wikipedia “Free Space Loss does not include factors such as the gain of the antennas used at the tranmitter and reciever”

So... 20 * Log10 (2400 MHz) + 20 * Log10 (22,300 Miles) + 36.6 is about:
191.2 dB

The only thing I learned from this how to scramble like mad when deadlines are due. I would have much rather had this material in my book where I could have read it before 8 hours from its due date. Then I might have actually had the time to absorb it and let it make sense. Now I'm just puking information onto paper.

I hate teachers who teach stuff not in the book!

That happens in virtually every class over here! I was once told that you should use void main() instead of int main() beacause int main() can cause your program to slow down !

Huh? Read this.

[KYA]

I agree doing stuff outside the textbook is excellent for learning, but the teacher should at least give you a grasp on how to solve it; not here it is, go onto wiki and look

on a side note: HOORAY FOR THE INTERNET!

maybe you should re-read Louisda16th's post.

I mean his teacher. Not Louisda16th

[jjhaag]

pretty sure he's not a member.

[Louisda16th]

She'd be much smarter if she were a member! There have been worse things as well. Example: "all polynomial functions are periodic". We were told this while being taught fourier analysis.

reciting the book is stupid, teachers say what's not in the book to shed light on new ideas, not reiterate something a student is already supposed to be doing. office hours and TAs are to help you if you have problems with either.
