Actually EM field is in the media between inner conductor and outer conductor of the cable. It is the EM field that is carrying the energy. There is no EM field inside conductor.
If the media between two conductors is vaccum, EM field will still exist.
I am not sure what exactly your...
I need to solve differential equations with initial conditions. I type the following into the Maple, however, I was told ERROR. Does Maple accept differential equations in symbolic form? How can I solve this problem?
Your light is sincerely appreciated...
Re: Question about C code
Yes, for that assignment, I did it wrong.
It is:
char const * const buffer;
char packet[8];
......
buffer = packet;
Cool~!
I don't know there is cdecl under linux as such a good helper. :)
But cdecl gives me "parse error" for "char const* const buffer", which I...
Re: Question about C code
what if it is:
const char * const buffer
or
const char * const * buffer
So, if I have:
buffer = char packet[8];
for 1), I can change the contents of packet, but can not change the location that buffer points to;
for 2), I can not change any element in packet...
VHDL coding style
Search Xilinx website, there is a good document about HDL code style.
also search the forum, you can find out many helpful posts. Try it :)
Help video codec
Try to think about the whole design first, find out input/output requirements, and decide how to spli the design to modules, then, give as much as possible definitations of each module, see whether you need and how to modify the algorithm to fit the hardware device.
Also, you...
In Quartus I could not find how to change the memory initialization file during simulation without re-compile. :( As I remembered, in Max-Plus you just need to reload the new .mif file, no need to re-compile the project.
Who knows how to do it in Quartus?
Thx a lot.
