A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more sophisticated ...

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

With so much analog-circuit design being done by automated tools and circuit-performance analysis done with tools such as Spice, it may seem anachronistic to actually go through a basic circuit in ...

Chaos Theory has been an important pursuit of physicists and mathematicians since it was brought to the forefront as a distinct phenomenon in the early 1960s. This early exposition got the attention ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components ...

The circuitry we rely on today comes from what could be considered a top-down approach, with the wiring completely laid out before it's etched into silicon. With the advent of nanotechnology, however, ...

My research projects in the area of nonlinear systems deal with finding dc operating points, steady state, and transient responses of electronic circuits. These are essential tasks in electrical ...

We always stress how efficient electric cars are. It is important to have that in mind, and Jason Fenske recently reminded us of that with a video about the huge impact tires can have on EVs. Texas ...
