In quantum devices, frequency modulation is utilized in controlling interactions. A new article discusses the physics of frequency modulation in superconducting quantum circuits, ultracold atoms, ...

High-performance frequency synthesizers are instrumental to modern radio, wireless, and telecommunication systems.

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...

[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the electronics ...

The diagram utilizes two BC548 transistors, more importantly descent results although not as good as RF transistors which provide high performance at wide bandwidth. It also utilizes electret ...

Spread spectrum clocking (SSC) is used in many computer interfaces such as PCI Express and Serial ATA to improve the EMI performance of the interface. It takes the form of frequency modulation (FM) of ...

In our recent feature on tremolo, we described how a valve can be configured to create a low-frequency oscillator (LFO) that can modulate amplitude. You can’t actually hear the oscillator itself, ...

Scientists recently developed a low-power version of the 60 GHz radio frequency integrated circuit (RFIC). The research team said that their RFIC draws as little as 67 mW of power in the 60 GHz ...
