Club Night Talk: Frequency Modulation

Bryan Harber presented a review and hands-on demonstration of the nature and mechanics of Frequency Modulation. Beginning with a demonstration using a signal generator and oscilloscope he visually demonstrated how AM “works” and then explained why FM cant be demonstrated visually the same way. Instead a spectrum analyser was used to do this. Discussion on multiple sidebands, bandwith and “channels”, “capture” and other licence-relevant matters followed. Slides to follow.
