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, ...
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 ...
Nisshinbo Micro Devices, a Tokyo-based semiconductor company, has unveiled a new quad-channel power management integrated circuit (PMIC).
Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...
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 ...
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 ...
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 ...
