On a typical Wednesday night, Ian Thurston twists knobs and punches buttons on a big mixing board at the casino where he runs sound for onstage talent. But tonight at Pacific Pizza in Browne's ...

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.

This article describes how to design and build an adjustable, encoder-controlled, two-range sine / square wave oscillator using the SLG47004 IC. To design a simple analog sine wave oscillator (using ...

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 ...

This file type includes high resolution graphics and schematics. Although quite a few direct digital synthesis (DDS) ICs can generate high-frequency sine waves, their complexity excludes them from ...

This is a very simple square wave generator circuit built with IC 74LS00 that can generate square signals with frequencies between 20 Hz and 1 MHz. Its stability is good enough for most applications.

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 ...

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 ...
