A common problem encountered by circuit designers is producing the manipulating the sine wave function. Since sine wave circuits represent a constantly controlled linear oscillator, they pose a ...

A description of a four-phase RC oscillator of a sinusoidal and rectangular shape is given. A triangular-shaped signal is obtained by the counterphase addition of half-waves of sinusoidal signals ...

Despite the name, electrical harmonics are terrible for data center harmony.

At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...

The power quality of electrical distribution systems has a drastic effect on power regulation and consumption. Power quality includes all aspects of events in the power system that deviate from normal ...

Fellow writer Charles S. “Buc” Fitch penned a multi-part series on backup power generators in the the Feb. 7, April 18, June 13 and Aug. 8 issues of Radio World Engineering Extra. (Read them at ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

Burst sine wave electroporation was found to cause less damage to cells and tissue but more disruption to the blood-brain barrier. Tackling brain cancer is complicated, but groundbreaking new research ...
