micro controller project
before doing the project you should learn the programming language 'C' (or assembly language is also enough). first choose the controller type..
Normally AT89s8252 can be used to do most of the projects and it is the one which is cheap and easily available
modem and broadband
Hi
Normally copper cable can be used for frequencies upto 1.1Mhz
But for voice communication, 30Hz to 300Hz will be enough. So, in earlier days for every telephone line
they used a low pass filter which will pass only upto
3KHz so dial up modem can utilize max of 4Khz...
u can refer 8051 Programming by Mazidi & Mazidi
there u can find the coding itself for serial communication and details abt Max232 & Max233.
Circuit also is there... and explanation why u r choosing a particular mode etc..

ADSL,VDSL,HDSL,SDSL are its variants..
A - asymmetric...inwhich download speed is greater than upload, preferable for
home users (80:20)
H - High bit rate variant
V - Very high bit rate...
Impulse response of a linear system is the response of a system when input is impulse.
When we apply impulse as input to a system ,the o/p of the system is called impulse response.

Semaphores let processes query or alter status information. They are often used to monitor
and control the availability of system resources such as shared memory segments
A semaphore is a protected variable (or abstract data type) and constitutes the classic
method for restricting access to...
