Overcoming conventional technological limitations to realize high-speed optical coherence modulation at 350 kHz. Structured ...

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 ...

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 ...

Frequency errors As mentioned earlier, the MS needs to adjust its transmission as per the ranging code from the BS. The transmit center frequency should be within ±2 percent of the subcarrier spacing ...

NTT Corporation and Tokyo Denki University have succeeded in further stabilizing the graduated frequency of an optical frequency ruler generated by modulating the intensity and phase of laser ...

Santa Clara, Calif. – January 22, 2013 – Redfern Integrated Optics (RIO), a global leader in single frequency narrow linewidth lasers and laser systems, announced the availability of its ORION™ ...

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 ...
