Oscillators and pulse-generators using operational-amplifier ICs have been proposed by many authors. Such generators can be found in a flood of articles in journals, magazines, books, and IC ...

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 ...

A small audio test generator is very useful for quickly tracing a signal through an audio unit. Its main purpose is speed rather than refinement. A single sine-wave signal of about 1 kHz is normally ...

If these signals exhibit a simple, periodic waveform, such as with sine, square, or triangular waves, the generators are called function generators. They are often used to check the function of ...

International Solid-State Circuits Conference in San Francisco always seems to make space for audio amplifier developments, and this year is no exception, with some extraordinary distortion and noise ...

Most audiophiles and enthusiasts have grown up with at least a basic understanding of what an amplifier does. It takes a tiny alternating electrical signal that represents the moment-to-moment ...
