The Exar XR-2206 function-generator IC cangenerate square, triangular, and sinusoidalsignals with low distortion. Its outputfrequency is inversely proportionalto the components in an RC ...

In the ham radio trade, gear such as the old Drake units [Dr. Scott M. Baker] has in his radio shack are often referred to as “boat anchors.” It refers to big, heavy radios that were perhaps a bit ...

Many power ICs use frequency jitter, which spreads a control signal's spectrum, to control EMI (electromagnetic interference). If you need to add frequency jitter to power ICs that control three-phase ...

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

Lasers normally emit only one color, or frequency of light. This is true for laser pointers or the laser diodes in a DVD player. [Kevin] caught wind of state-of-the-art research into making variable ...

Synchrotek, Inc. offers a line of standard and custom electric generators that feature variable speed input, which permits the power source to rotate at its optimal speed. This arrangement is ideal ...
