This simple circuit has been designed to generate sine waves with a frequency of 1 KHz while featuring low distortion and low output impedance until 1 V RMS as it obtains power from batteries. Sine ...
A Microchip PIC16F628 is used as the controller chip for this low cost and simple Since/Square wave generator based on the Analog Devices AD9835 Direct Digital Synthesis (DDS) Generator chip. The ...
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 ...
Microcontroller addict [Debraj] decided to make his own programmable sine wave generator, and was able to put it together for under $40 USD. Other than low-cost, his list of requirements was as ...
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 ...
