When designing bass reflex loudspeaker cabinets, it is necessary to measure the resonance of the speaker to an accuracy of about 1%. To do this, you need an audio oscillator and a frequency counter.

Crystals usually operate at fundamental frequencies up to about 15 MHz. Whenever higher frequencies are required a frequency multiplier is placed after the crystal oscillator. The resulting output ...

How to implement a frequency multiplier. How to create circuit designs in the GreenPAK Designer software. This article describes how to implement a frequency multiplier using a GreenPAK programmable ...

The phase locked loop, or PLL, is a real workhorse of circuit design. It is a classic feedback loop where the phase of an oscillator is locked to the phase of a ...

Higher frequencies mean faster data transfer and more powerful processors. Technically, however, it is anything but easy to keep increasing clock rates and radio frequencies. New materials could solve ...

A new discovery by physicists could make certain components in computers and smartphones obsolete. The team has succeeded in directly converting frequencies to higher ranges in a common magnetic ...

Using nonlinear crystals to convert the frequency of a laser gets a new look as an Italian researcher unveils a 3/2 frequency multiplier that could simplify RGB laser systems. Multiplying the ...
