If you’ve seen a big air-variable capacitor, you may have noticed that some of the plates may have slots cut into them. Why? [Mr Carlson] has the answer in the video below. The short answer: ...

A grouping of Mitsubishi Electric’s AC drives or variable frequency drives (VFDs). In the competitive landscape of machine design, engineers in food, pharmaceutical and manufacturing sectors face the ...

Injection locking [1] can not only improve oscillator frequency stability and phase noise, but act as a selective frequency divider as well [2][3]. You can find sample setups of a simple ...

Abstract: This work deals with the realization of oscillator-based resistive sensor interfaces using a second-generation voltage conveyor (VCII). In particular, novel configurations of sinusoidal ...

AC induction motors are widely used in industrial applications due to their reliability and low maintenance needs. Comprised of a stator and rotor, these motors convert electrical energy into ...

Abstract: A well-known tunable active-RC oscillator circuit is adopted with the use of modern current feedback amplifiers (CFAs) and analyzed for its performance characteristics. Its performance ...

A staple of the radio amateur’s arsenal of test equipment in previous decades was the dip meter. This was a variable frequency oscillator whose coil would be placed near the circuit to be tested, and ...

Let us get down to basics. Conceptionally, a ring oscillator is a deceptively simple self-oscillating electronic oscillator that consists of a series of several inverters, where the output of each ...

Written by Bernard D. Beitman M.D. and Ruslana Remennikova, MS. Since the beginning of human civilization, history has shown a correlation between sound and cognitive, mental, and physical wellness. 1 ...
