Keysight’s Electrical Performance Scan (EP-Scan) is a digital simulation tool for hardware engineers and PCB designers that performs rapid signal integrity analysis. EP-Scan provides diagnostics to ...

Transmitting Antenna The radio signal travels to the antenna. The signal creates a corresponding electromagnetic field -- a radio wave. This radio wave moves outward in all directions.

I discuss both the unpublished recorded and published evidence of Prof. Henry's out-of-doors electrical signal transmission experiments of October 1842 and October 1843. Mention is made of the ...
