mic_k86 Posted January 31, 2009 Report 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... Quote
Donald Posted January 31, 2009 Report Posted January 31, 2009 There is a modulation toolkit available for LabVIEW. Check the National Instruments site for more information. Quote
Maca Posted January 31, 2009 Report 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
mic_k86 Posted February 1, 2009 Author Report Posted February 1, 2009 any example for reference? Quote
