X10 is a protocol for communication among electronic devices used for home automation (domotics). It primarily uses power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information. A wireless radio based protocol transport is also defined. X10 was developed in 1975 by Pico Electronics of Glenrothes, Scotland, in order to a...

LED brightness adjustment: high-frequency PWM dimming – Power House – Blogs – TI E2E Community

Posted on by delta
In one of my previous blog posts, I introduced different dimming methods for light-emitting diode (LED) drivers: analog and pulse-width modulation (PWM) dimming. In this post, I will elaborate more on PWM dimming and how to get its frequency fast enough in order to reduce its effect on humans or other living creatures. Let’s review why PWM dimming is preferable to analog dimming in some applicatio...

And of course, sectors to feed the masses.   Enter the AF-FX11. First step was to call a coordinator (I called Liz at Intelpath) to check on spectrum availability. I was a bit concerned by all the nay-sayers stating that there are almost no 80 mhz wide ch...
