Impressively, the unit registered the lowest frequency loss of any chip to date. Specifically, the engineers noted that the new chip was 15x more stable and 100x more efficient in terms of microwave ...

Modulation advances have fueled more efficient use of bandwidth, although conventional modulation formats still require allowance for upper and lower sidebands around the carrier frequency. Ultra ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

Recent TE wave measurements of the electron cloud density in the beampipe at CesrTA and DAFNE have shown that, especially near cutoff, the microwave excitation takes place by coupling to a standing ...

Xperi and several U.S. broadcast groups are pushing back against an effort to modify the FCC’s order allowing asymmetric digital sidebands. In September the commission allowed most FM stations to ...

The low-mass X-ray binary pulsar 4U 1626-67 shows 0.048 Hz quasi-periodic oscillations (QPOs) and red noise variability as well as coherent pulsations at the 0.130 Hz neutron star spin frequency.

Abstract: We describe a microwave amplitude modulator capable of operating at high modulation rates (limited by mixer IF port bandwidth) with minimal residual phase modulation. The modulator is based ...

A vote by all five Commissioners at the September Open Meeting on a plan that would streamline the process for allowing digital transmissions at different power levels on the upper and lower digital ...

Emerging, data-intensive technologies like artificial intelligence and machine learning are gaining popularity. Data centers, which act as the essential infrastructure for these technologies, need to ...
