For high-speed and large-capacity optical communication applications and improvement of accuracy in microwave generation and evaluation equipment Results: NTT and their partners have developed a ...

Since the conception of the laser frequency comb in the late 1990s, it has revolutionized the precise measurement of frequency and time. Beyond their initial use in optical clocks and precision ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

Long-range couplings between lattice sites algorithmically speed up the efficiency of quantum walks. Scientists in China propose to construct one-dimension discrete-time quantum walk (1D DTQW) in ...

Oscilloscope measurement parameters provide accurate measurements of acquired waveforms. Most digital oscilloscopes offer around twenty-five standard parameters like frequency, peak-to-peak amplitude, ...

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...
