Well, in that case, I guess this is an expert question on a transceiver system. No wonder the book has a considerable gap between the FFT explanation and digital signal modulation.
Does anyone have a pointer to understand the matters within the gap?
HiHo!
W. Stallings's "Wireless Communications & Networks, 2nd edition" explains the relationships between bandwidth and Fourier transformation by depicting a square wave. The square wave is approximated with a Fourier series having several sine terms. The bandwidth is then defined by the...

Moonbear:
What is the most recent concept accepted among modern psychology scholars?

No, I'm not joking. I am not a psychology guy and trying to find the truth out :-)
"alchemy" under "chemistry"? I didn't realize that it is the situation. In that case, what is the right...
Hi Ho!
Referring to http://en.wikipedia.org/wiki/Four_Temperaments under "Temperament Blends", I would like to discuss whether it is possible for a person to have a blend of sanguine and melancholic at the same time.
AFAIK, a sanguine tends to be sloppy while a melancholic tends to be...
Yes, I read your previous post. I just want to ensure myself that there is really no "another method" out there. Thank you for telling me about what happened to the mathematician :smile:
Thank you for all of your help.
Best regards,

Well, if I just tried to find out the answer, that fact would be enough for me. But, I want to know how in the past someone would be able to obtain that answer. Suppose a mathematician in the past encountered the same class of problem. Of course, the mathematician would have tried the...
I have taken a look at the page on Wikipedia but it does not explain anything how a series of non-terminating integration by parts can be transformed to an exponential integral.
Could you please tell me how to do the transformation? Or, is there any pointer to a webpage that shows how to do...

Hi Ho!
I think you can easily solve your problem if you imagine you have the following objects:
1. MarkedWheel
2. MarkedWheelsPermutationMachine
A marked wheel is a wheel that can be turned in only one direction.
Each turn will display one mark on its surface.
A permutation machine...
Because when I asked it for the very first time (09.17.07), I didn't know the reason.
But, I encountered a case where I would like to mount a filesystem in a non-empty directory.
So, I wrote the reason here on 03.22.08 to let others know.
Best regards,

Hi Ho!
One reason to mount a file system on a nonempty directory is when the whole content of the directory will be rendered useless with the content of the file system to be mounted. For example, a DVD contains four ISO9660 image files of four different titles of games has been mounted under...
If you use Java, you can just use its built-in function to do so:
int fromBase = 10;
int toBase = 2;
Integer.toString (Integer.parseInt (args [0], fromBase), toBase);
Next, you can just run your program conveniently like:
java BaseNToMConverter 82733
