This is a nice visual, but it doesnt show anything. Water ripples is all i can see right now to visualize. Could probably do full cancellation as well as degrees of attennuation Thinking out loud here... If i had a tray of water, and a respectable camera. If i dropped a stone on the left

Even two lights doesnt cancel, it mixes. Remember, im looking for laymen. This is to explain to the boss why particular customers need fired, and then to explain to the customer why they are being fired so they dont go nuclear on usnin our coverage area On Sep 27, 2017 10:06 PM, "Josh

"Sometimes the wind blows and the leaves move. This changes where the light moves." Almost everything in RF can be visualized with light. Some things are harder than others (ducting for example). On Sep 27, 2017 9:49 PM, "Steve Jones" wrote: > Laymen, laymen, laymen.

I understand phase cancellation, you understand phase cancellation. Now imagine youd never seen an oscilliscope. Visualize that On Sep 27, 2017 9:54 PM, "Jaime Solorza" wrote: > Look up phase cancellation > > On Sep 27, 2017 8:49 PM, "Steve Jones"

Above example to get variance\variability across woul be smash the fingers on a table, then smash the fingers in a tub of water. The finger smashing in the wayer would have less force, theyd understand that. I wish everybody had the mindset of those who grew up in the 50s, where smashing fingers

Laymen, laymen, laymen. How do i visualize the fact that the same thing at the same level, can cancel itself out? Beyond that, how do i show the variance factors, temp, humidity, radio mites? Even better would be a live display of reasonable things they understand. My old man would be easy. Id

[AFMUG] Multipath fading for a laymen (visuals please)

I have a location thats solely down to multipath reflective fading. The best analogy i have is noise cancelling headphones, which makes total sense to me... but still the same dull look. Is there aome rf for dummies visuals?
