Whenever I find myself harboring a constantly nagging thought, I know I will eventually have to get busy and find a way to put it to rest. When I read EDN’s Design Ideas, I look for the range of ...

I became aware of harmonics and the sound of different shaped waveforms early in my electronics career (mid 1970’s) as I was an avid fan of [Emerson Lake and Palmer], [Pink Floyd], [Yes], and the list ...

I love all about electronics, circuit diagrams and crazy projects that can help us achieve almost everything our mind can conceive. I created this website and I want to invite you to participate in ...

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.

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 ...
