A new radio design from the University of Texas may have found a way to transmit and receive data simultaneously, without the need for specialized software networks. Could this new technology ...

This file type includes high resolution graphics and schematics when applicable. A most critical device in an optical networking system is the laser diode, since it’s responsible for converting the ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

[Hans Rosenberg] knows a thing or two about RF PCB design and has provided a three-part four-part video demonstration of some solid rules of thumb. We will cover the first part here and leave the ...

voltage. Often a passive single-pole RC filter will satisfy design requirements, but this approach typically suffers from several drawbacks including slow response time, noisy results, and having an ...

The circuit diagram illustrates the creation of a plain microphone setup using two resistors to produce an aggregate amplifier, designed for use in computers. A microphone, originally created by Emile ...

Measuring dynamic currents with an oscilloscope is challenging, but this updated differential current probe makes it simple ...
