Manipulations of multiple carrier frequencies are especially important in a variety of fields like radar detection and wireless communications. In conventional radio-frequency architecture, the multi-frequency control is implemented by microwave circuits
In the chip manufacturing process, these timing criteria are not met on the first try. After several interactive back-end flow runs, the timing requirement is successfully met, and only then, the chip is taped out. In this article, we will discuss the methods that are used in back-end fl...
This possibility of real-time quality assurance would be a step forward with respect to other frequently used two-step approaches, such as real-time MR-MOTUS (Huttinga et al., 2021c), since it is not trivial to give a degree of confidence in the estimates provided by such methods, even...
The primary novelty of the present work distinct to our prior work is that it shows the potential of limb BCG for wearable BP monitoring. Specifically, it elucidated the typical shape of the wrist BCG waveform, and it also demonstrated the wrist BCG features relevant to PTT calculation with ...
This is followed by some examples in chapter 12 about how to initialize the RTC and how to set alarm and timer. Providing backup power when the rest of the system is not powered is covered in chapter 13. In order to make a reliable and accurate application it is important that the PCB...
Chronos, known as"time" in Ancient Geek, is thehigh-availability,high-performanceservice to provideglobally strictly monotone increasing timestamp. Chronos uses standby architecture so that when the master server is down, any backup server could notice and take over the service. We useThriftas RPC...
However, when the nonlinear systems contain unknown functions, the backstepping-based control schemes are not feasible. Unfortunately, the assumption that the nonlinear system under consideration is totally known is quite restrictive for a variety of engineering systems. To relax this assumption, the ...
This paper applies the time-frequency domain combined analysis method to the long-term changes in visibility in China and analyzes the specific changes in visibility in the frequency domain. Visibility is closely related to people’s lives, and poor visibility can have adverse effects on people’s...
Also, if the FSET/SYNC pin is pulled low, the IC will not power-up. More information on the FSET/SYNC pin can be found in the Sync section of this datasheet. Switching Frequency (MHz) 2 1 0.800 0.600 Detection Time (ms) 1.5 to 2 3 to 4 3.75 to 5 5 to 6.7 The LED pin ...
The topic of ``pitch detection'' in the signal processing literature is often really about fundamental frequency estimation [106], and this distinction is lost. This is not a problem for strictly periodic signals. Mathematical Definition of the STFT The usual mathematical definition of the STFT ...
