To achieve the datasheet performance of ultra-high-speed data converters, now clocking to 64 GS/sec, the handoff to and from the microwave domain must be near perfect. To preserve the data converters’ spurious-free dynamic range, a new category of component has been developed that converts between the differential and single-ended signal domains while amplifying and filtering out-of-band signals.
Inside the Sphere in Las Vegas is a 15,000 m2 (160,000 ft2, 4 acres) 16K resolution wraparound LED screen with over 170 million pixels. It’s 240 feet high and wraps around the audience to create fully immersive visual effects. The entire visual content generation and control system is completely redundant to ensure uninterrupted entertainment. This […]
The Sphere’s immersive spatial audio system is powered by 167,000 amplifier channels and sophisticated multilayer speaker arrays. This FAQ begins with a review of the amplifier technology, looks at the structure of the speaker arrays, and closes with the audio beamforming technology used to create spatial audio in the Sphere. The 167,000 channels of amplification […]
The Sphere is all about entertainment. The entertainment incorporates numerous special effects, including infrasonics and haptics, to create 4D environments. In this case, “D” doesn’t refer to a physical dimension; it refers to additional sensory inputs beyond audio and visual. This FAQ reviews the use of moving magnet linear motors and class D drivers and […]
High-precision stereolithography offers an innovative way to create active and passive components for the 100-GHz and even terahertz range.
It takes a unique facility plus customized hardware and software to create the content seen in the Las Vegas Sphere. This FAQ looks at the production facility where the immersive content is developed, the custom 16K resolution video camera used to record video content and the customized software for creating the immersive audio. Until the […]
The $2.3 billion technological marvel, the Las Vegas Sphere, opened Friday, 29 September 2023. It’s 112 meters (m) (366 ft) high and 157 m (516 ft) wide at its broadest point. It’s the largest spherical building in the world at 81,300 m2 (875,000 ft2). It includes seating for 18,600 people, and all seats have high-speed […]
Phase noise requires more than one instrument unless you use a phase-noise analyzer.
Phase noise is an artifact of a nonideal oscillator and is best investigated in the frequency domain. Phase noise accompanies the generation of any real-world sinusoidal signal. You can think of it as the analog equivalent of digital jitter, which we covered in an earlier series (read part 1 and part 2). Recall that jitter […]
An electric vehicle (EV) battery state of charge (SOC) represents energy levels as a percentage. Analogous to an internal combustion engine (ICE) fuel gauge, SOC clearly indicates available energy that directly corresponds to the driving range. This article explains how SOC is calculated and explores the different methods used to determine these calculations. It also…
