A new treatment that uses electrodes to deliver alternating pulses of ultralow-frequency (ULF) current could help address this need. In a pilot trial, the treatment improved pain ratings by as much as ...

In addition, Figure 4 shows parameters such as modulation frequency (f M), span, and the modulation index (m) that impact the performance of the FSS, where T M is the modulation period.

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 ...

The team put an electro-optic modulation element into a lithium niobate comb microresonator, according to their journal article. A lithium niobate resonator was able to tune the bandwidth and ...

FREQUENCY-MODULATION, or the technique of varying the frequency of radio waves for signalling purposes, has been known and used for many years ; but it was not until Armstrong in the United States ...
