mic_k86 Posted January 31, 2009 Report Share Posted January 31, 2009 hi all, i have one project here, but i no idea how to do it. the question is as below: using computer simulation, demonstrate that an FM signal can be demodulated using: a. slope detection b. a zero crossing detector help...

Donald Posted January 31, 2009 Report Share Posted January 31, 2009 There is a modulation toolkit available for LabVIEW. Check the National Instruments site for more information. Quote Link to comment
Maca Posted January 31, 2009 Report Share Posted January 31, 2009 Both are pretty straight forward: plot the time difference between the zero crossing or zero slope points and you should have a pretty graph of the modulation (with a DC offset). Quote Link to comment
mic_k86 Posted February 1, 2009 Author Report Share Posted February 1, 2009 any example for reference? Quote Link to comment
