While doing some work on Audio Amplifiers and Light Organs in 2016 I needed a simple (and not neccessarily absolutely precise) Function Generator to generate sinus ...

This project is a dual-channel function generator. Waveforms are generated digitally inside an FPGA via DDS (Direct Digital Synthesis). The main purpose of this project was to get familiar with FPGAs ...

After going through the recent Elektor FPGA Board article series, I wanted to put my FPGA board to some practical use while gaining more experience in VHDL programming, learning by doing. After going ...

A lifetime of amassing random pieces of test equipment has left me with a gap in my armoury, namely that I don’t possess a low frequency function generator. This could easily be addressed, but for two ...

Abstract: A stable oscillator for generating a wave is one of the important parts for wireless charging system. There are many methods to establish an oscillator featuring with some advantages, one of ...

The model B8040FD DDS function generator provides sinwave outputs from 1 µHz to 40 MHz with harmonic distortion less than −54 dBc and stability of 1 ppm short term and 40 ppm long term. It it can also ...

Three new DDS (direct digital synthesis) sweep function generator models have been announced that generate stable and precise sine, square, and triangle waveforms for education, training, and other ...

Three measuring instruments in one compact housing, physical buttons, and a touchscreen—that sounds like a smart combination. Fnirsi continues to rapidly launch new measuring equipment, and with the ...

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 ...

Abstract: DDS direct digital frequency synthesis, is a key digital technology. The system to DDS technology as the core, consists of AD9910, STM32 module, TFTLCD display module, filter circuit, ...
