PIC 18F4220 for NRZ (Non-Return Zero) signal... | Piclist

A discussion group for the PICMicro microcontroller. Also called the Microchip PIC, this list is dedicated to the use and abuse of this fine, simple, microcontroller. Close to topic posts are welcome, ie. general electronics.

hello!

sorry for disturbing...

i am now doing a project using MC PIC 18F4220. it is actually a fiber
optics project, but i've been assigned to complete the receiver part
which includes front-end, digital signal processing and other two more
parts. i'm doing only the digital signal processing part and i need to
use PIC18F4220.

actually, my level of electronics is very poor. after reading through
the Microchip PIC 18F4220 datasheet, i don't even understand even 5%
of it.

i simply explain my project like this:

- the digital signal processing part (DSP) will receive signal from
the front-end (FE).
- because this is a multilevel transmission system project, for
assumption and example, there will be 4 signals coming from FE to DSP.
- by using Non-Return Zero (NRZ) modulation, these 4 signals will be
combined and transmitted into PIC18F4220.
- through the PIC18F4220, the signal will be processed and the output
will be 4 signals which are identical to the original signals.

i really need help for this project. there are 40 pins on PIC18F4220,
and AT LEAST, can anybody please help me to show at what pin...
(a) to insert A signal (one signal) to the PIC18F4220?
(b) to insert 4 signals to the PIC18F4220?
(c) to measure the output of (a)?
(d) to measure the ouput of (b)?

i really need help from all of you guys and i really appreciate it.
thanx a lot!
