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 ...

Heading Protek's B8000FD series of dual-output DDS function generators is the Model B8040FD, an instrument that operates from 1 µHz to 40 MHz with harmonic distortion of less than –54 dBc for sine ...

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 ...

In DDS-mode, only a few commands are needed to e.g. generate a sine wave (orange block), accelerate the frequency (blue block) and lower the amplitude (green block). 23 different AWGs are able to use ...

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 ...

The sine-wave generator indicates the piston position as a function of time. The piston motion is simple harmonic and goes between the top dead center (TDC) position and bottom dead center (BDC) ...

We needed a handheld, battery-powered signal generator with a sine-wave output that was continuously adjustable from 100 Hz to 10 kHz. For such a wide frequency range, we selected a function-generator ...

Over on YouTube [Andrew Neal] has a Function Generator Build for Beginners. As beginner videos go this one is fairly comprehensive. [Andrew] shows us how to build a square-wave generator on a ...
