Finding that his recently purchased LED Christmas lights defaulted to an annoying blinking pattern that took a ridiculous seven button presses to disable each time they were powered up, [Matthew ...
The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.
Editor's note: This article is the first of two parts. If you spend any time on a test bench, you probably use square waves to test components, subsystems, and systems. You can get square waves from ...
Philosopher Mark de Silva's debut novel, Square Wave, shows what a novel can do when it goes off the beaten track. In it, de Silva attempts to structure chaos by following patterns that might emerge ...
The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...
Many microcontrollers or PICs will have uncommitted digital-to-analog converter (DAC) outputs that can be used to generate sine waves. But these are generally low resolution (8 to 10 bits), yielding a ...
A FISHING crew was stunned when they found themselves surrounded by a dangerous square wave phenomenon. Square waves are caused by two wave systems travelling at different speeds and trajectories.
A waveform that rises quickly to a particular amplitude, remains constant for a time period and drops fast at the end. In digital systems, square waves are the norm, because they represent a binary ...
An audio waveform theoretically comprised of an infinite set of odd harmonic sine waves. It is often used in sound synthesis. See also: Fourier Theorem, Law of Superposition, Oscillator, Switch.
