Last month, I talked about how to get started with mBed and ARM processors using a very inexpensive development board. I wanted to revisit mBed, though, and show something with a little more substance ...

The project was designed to build a frequency generator based on 555 timer that can be used as a body zapper. The project was designed to build a frequency generator based on 555 timer that can be ...

How to create a wide range of complex signals using simple, cheap microcontrollers. A simple process for generating complex signals utilizing standard software tools. Often during product development, ...

A signal generator is a handy bit of kit and with the right components, it’s pretty easy to build one. Fabricating a proper signal generator probe is another matter entirely. [Frank]’s DIY signal ...

This direct digital synthesis IC can function as an arbitrary waveform generator by bypassing the SIN table ROM, holding the phase accumulator at zero, and using the phase register as the ...

AC testing of electronic systems often requires a low-distortion signal source to excite a DUT (device under test). Instead of using a signal generator and a power amplifier to produce a ...
