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?

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. -- Tim Wescott Control systems and communications consulting http://www.wescottdesign.com Need to learn how to apply control theory in your embedded system?

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
