When discussing electronic circuits, I often lock onto the circuit's magnitude characteristics. For example, we refer to filters as high pass, low pass, or band pass, which is a shorthand way to ...

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 ...

This article is part of the Ideas for Design Series: Vol. 3, No. 7. This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals ...

There are several ways to evaluate the bandwidth of a signal in the time domain and frequency domain. Previously we looked at the classic relationship of rise time (t r) and bandwidth (f 3db) [Ref 1], ...

Square wave voltammetry (SWV) is a sophisticated electroanalytical technique that utilises a superimposed square-wave potential on a staircase waveform to investigate electrode reactions with high ...

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.

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.

[Voja Antonic] has built a clock that tells the time in binary with square waves, and trolls the uninitiated in electronics. The clock itself is very attractive. If you look closely you can see the ...
