This advancement was made possible by joint progress in communication theory, devices technology and system and circuit design ... Some examples are wireless local-area networks (WLAN), sensor ...

In a superheterodyne radio, a local oscillator is an electronic circuit that generates a frequency based on the desired channel. The output of the oscillator is the channel frequency typically ...

and have the effect of reversing the polarity of the path between them on each cycle of the local oscillator. It is used in synthesisers and guitar pedals, and in radio circuits wherever a ...

This section examines inductors and capacitors separately, and then in combination, to determine how they function to tune a radio s RF, intermediate-frequency (IF), and local oscillator (LO) circuits ...

Figure 2 A LPF RC equivalent circuit that provides excitation for quartz oscillator. Assuming the rising threshold Vt1 and the falling threshold Vt0 are symmetrical (the case of 54HC14), the frequency ...

Here's why he prefers the oscillator: "But the Oscillator was something that Karen Cramer said to me, that what you have to do is you have to find some gauge that measures whether people are too ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

Changing either circuit can spoil this balance unless there is a feedback circuit to keep it in check. This could be with a sense coil, a local antenna or something more direct, like in this case.

Scientists have utilized a device based on the Duffing oscillator to solve the problem of PV systems' low efficiency at low ...

The Hayek Oscillator is a non-invasive high frequency ventilator which offers the first real alternative to conventional mechanical ventilation and enhances secretion removal. The Oscillator ...
