Multiplexing was developed in the early 1870s, but it’s become much more applicable to digital telecommunications in the late 20th century. Today, frequency division multiplexing (FDM), time division multiplexing (TDM), and wavelength division multiplexing (WDM) have become an extremely important asset to telecommunication processes and has greatly improved the way that we transmit and receive independent signals over AM and FM radio, telephone lines, and optical fibers.

Parallel circuits are one of two fundamental circuit configurations we come across every day. Like a parallel universe, parallel circuits and networks can give us unexpected results. Adding more gives less, and voltage stays the same no matter what! Learn about the role resistance plays in parallel circuits for your designs and safety.

Rockchip has announced at COMPUTEX Taipei that it has launched the world lowest power WiFi technology RKi6000 jointly developed with a third party. This technology makes WiFi power consumption equal to that of BT4.0 LE (Low Energy). The receiving power consumption is around 20mA during use, which is 85% lower than state-of-the-art WiFi devices for the Internet of Things (IoT), setting a benchmark power consumption level that should renew the standard for WiFi power consumption in IoT smart hardware globally.
