Sawtooth- or exponential-ramp relaxation oscillators are common and generally easy to build. However sometimes a cleaner waveform is desired, and generators of even-symmetric waveforms are a bit more ...

This triangle wave generator is made with a trigger Schmitt that converts a triangle wave into a rectangular one used to charge and discharge a capacitor through current sources. The positive current ...

This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables, and other ...

This project designs a Function Generator using the UA741CP operational amplifier to produce square, triangle, and sine waves at adjustable frequencies. It demonstrates waveform generation, frequency ...

Abstract: An ultra-low power adjustable triangle wave generator with a multi tunable amplitude and frequency is introduced in this paper. The proposed circuit consists of a Schmitt trigger and a ...

Frequency (20 Hz to 10,000 Hz) via slider, buttons, or text input. Volume and balance sliders. Wave type selection (sinusoidal, square, triangle, etc.). Cross ...

Abstract: A general BIST architecture for A-to-D converters involves the integration of both an analog test signal generator and a digital output response analyzer. This paper presents a structure for ...

A signal generator that can produce the usual sine, square, and triangle waves is handy and has been a staple of electronic benches for decades. Being able to craft custom signals opens up new ...

This is a computer controlled function generator for the audio range. Waveforms: sine, rect, sawtooth, triangle, absolute sine and arbitrary, defined by formula.

This circuit, a modification of a function-generator circuit, comprises a battery-powered sinewave generator that is continuously adjustable from 100 Hz to 10 kHz. We needed a handheld, ...
