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, ...
Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...
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 ...
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 ...
Researchers from the University of Rochester and CalTech say they have created the first microwave-rate soliton microcomb that can control the repetition rate at a high speed. Microcombs are frequency ...
EPC and Analog Devices introduce reference design using a new Analog controller fully optimized to drive EPC GaN FETs. The combination of the new Analog LTC7890 synchronous GaN buck controller with ...
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 ...
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 ...

Everything you need to know about modulation, from Leslie speakers to vibrato, chorus and BBD chips
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, ...
