An unexpected revisit to my earlier post on mouse encoder hacking sparked a timely opportunity to reexamine quadrature encoders, this time with a clearer lens and a more targeted focus on their signal ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...

Part 1 of this FAQ looked at the optical rotary encoder, a low-cost, high-resolution, easy-to-use sensor for indicating incremental shaft position (although it can be “upgraded” to indicate absolute ...

Want to build a signal generator? Follow these tips about constructing a high-performance DDS signal generator using an AD9851. The topics of module modification, theory of operation, and software are ...

Abstract: Driving synchronous machines requires early and accurate knowledge of the absolute position of the rotor; current solutions based on resolvers, sin–cos, or absolute encoders are complex, ...

A rotary encoder is a type of electromechanical position sensor that can be used to identify the angular position of the rotary shaft. This type of sensor or module generates an electrical signal ...

Rotary encoders have been key components in motion and position control systems since the earliest days of digital controls, translating rotary motion into digital feedback signals for control systems ...

Interruptions aren’t just a staple of our daily lives. They’re also crucial for making computer systems work as well as they do, as they allow for a system to immediately respond to an event. While on ...

More than 7 years ago, Elektor published my 500 ppm LCR Meter AU2013. Since then I have developed a new LCR Meter, sacrificing a little on extreme accuracy for the sake of extended functionality. A ...
