  2. Ryan Metivier, Analog Devices EDN Home-based power-line networking signals are similar to xDSL (digitalsubscriber- line) signals in that they both typically employ a form of OFDM (orthogonal frequency-division multiplexing). Both applications ...

  3. Michael Whybray EDN Most desk fans I have come across have three speeds: Full Speed, Almost Full Speed, and Off useless if you want just a gentle air movement, and far too noisy if you are trying to get to sleep (in your bedroom of course, not at ...

  6. Guus Colman EDN In many applications, the frequency-conversion steps comprise a buffer, preferably with some extra voltage gain; a mixer; and some filtering. Instead of including an amplifier in front of the mixer, you can easily integrate the ...

  7. Keith Szolusha EDN In certain dc/dc-converter applications, on-chip, cycle-by-cycle current limit may be insufficient protection to prevent a failure during a short circuit. A nonsynchronous boost converter provides a direct path from the input to ...

  9. Art Hogrefe EDN A number of circuits, such as level detectors and AM demodulators, benefit from a rectifier with a low offset voltage. Silicon diodes have an offset of approximately 0.6 V and do not work well in low-level circuitry. A Schottky ...
