The first-generation integrator-hysteresis-switch FGs were replaced by a second-generation design scheme using current sources. The integrator-based FG loop can be improved by driving the integrating ...

In the first two parts of this article, the first two generations of triangle-wave generator loops were presented – the foundational concepts at the heart of function generator (FG) technology. This ...

It’s always a pleasure to find a hardware hacker who you haven’t seen before, and page back through their work. [Bettina Neumryr]’s niche comes in building projects from old electronics magazines, and ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

Numerous test-and-measurement applications require a high-frequency magnetic field. Oftentimes, high field strength is needed. Examples of such applications include bio-medicine research on the effect ...
