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.

New tunable capacitors from STMicroelectronics are meant to optimize signal-power transfer between a smartphone's antenna and power amplifier. Other improvements include lower parasitic resistance and inductance, which boost efficiency and reduce heat dissipation, and a higher ESD rating for greater robustness.

The LM35 is an ideal temperature sensor for measuring ambient temperature. It provides a linear output proportional to the temperature, with 0 V corresponding to 0 degrees C and an output voltage change of 10 mV for each degree C change. LM35s are easier to use than thermistors and thermocouples because they are so linear and require no signal conditioning.
The Arduino can input and output analog signals as well as digital signals.
