A Brief History of RF Pulse Modulation

This month we bring you a fascinating and interesting article on the history of RF Pulse Modulation. I hope you enjoy reading about Heinrich Hertz’s 1887 experiment that proved the existence of the 1887 electromagnetic waves, as much as I did.

Pulse modulation has been around for over 125 years. In 1887, German physicist Heinrich Hertz built the first experimental spark-gap transmitters (electromagnetic pulse modulators), with which he proved the existence of radio waves. 

In 1888, using 455 MHz radio waves, he studied the ability of radio waves to be reflected from metallic objects and refracted by dielectric media.  Hertz’s work spawing many other inventions.
