This is really two problems:
(1) find appropriate _algorithms_ for AM/FM demodulation - easy to do
via a search engine
(2) implement these algorithms in C in the form of a DLL -
straightforward C programming task
If you approach this one problem at a time then you should find it a lot
easier.
Good luck,
Paul

Is English perhaps your second language? It sounds like you want to have
the answer handed to you on a platter -- wouldn't that defeat the purpose
of a senior project?
I suggest that you go find some references on the web that include block
diagrams of FM and AM demodulators, then implement them in code.
Alternately, an ARRL (or, I believe, an RSGB) Handbook should have such
block diagrams.

hello
i am a final yr project student, and i have to develop c language
codes for am and fm demodulation ... i will have to create a dll file
which can bbe accessed by labview for display.
i could not find any specific directives towards software
implementation of am/fm demodulation...can somebody pls help me out?
