Monitoring volcanoes is complex, and it’s an important activity to ensure public safety in many areas of the world. It involves monitoring ground deformations, earthquakes and vibrations, volcanic gas, rock and water chemistry, and remote sensing from satellites. Volcano monitoring needs to be implemented on a continuous basis or in near-real-time and is an extreme […]
A bare-bones implementation of the Fast Fourier Transform helps illuminate how to extract frequency information from input data samples. In part 1 of this series, we reviewed the discrete Fourier transform (DFT) and manually calculated one DFT shown in Table 1. Table 1. Manual DFT results DFT input Complex DFT |DFT| 3 12 + j0 […]
Electronic engineers use advanced simulation tools to create virtual representations of complex electronic circuits. These ‘digital twins’ streamline the circuit design process, accurately modeling silicon behavior and performance before physical fabrication. This article reviews the three primary circuit simulation categories: analog, digital, and mixed. It also discusses different simulation levels, such as block and chip, […]
This multipart series will review the discrete Fourier Transform and describe how to avoid common problems when transitioning from the time to frequency domain. A recent post on phase noise discussed expressing a function of time as a function of frequency. The Fourier Transform is the well-known road from the time domain to the frequency […]
The electrification of transportation, Industry 4.0, communications, agriculture, and other industries compliments the decarbonization of the utility grid to meaningfully reduce Co2 emissions. Integration of renewable energy sources will be a key to decarbonization of the grid, and artificial intelligence (AI) and machine learning (ML) will be used to enable wider integration of renewable energy. […]
Micro photo sensors have built-in amplifiers and are available in a variety of configurations, with modulated, non-modulated, and polarized light beams. They’re used to provide precise and stable sensing or positioning of materials, components, or assemblies. Some have integrated connectivity, like IO-Link and IP 67 environmental ratings. Uses for micro photo sensors include precision manufacturing […]
Metamaterial arrays allow the wireless medium and path to be “adjusted” to compensate for its many imperfections and changes.
In this article, we’ll explore the types of e-bikes available and their features. In terms of e-mobility, e-bikes stand out as a compact, affordable option for many.
Charged coupled devices (CCDs) and CMOS active pixel sensors (CMOS sensors) are the primary image sensor technologies. They rely on lenses and other optical components to deliver the image to be captured. This FAQ reviews the differences between CCDs and CMOS sensors, looks at some key specifications of image sensors and the concept of quantum […]
In this FAQ, you’ll learn how to know if your test application needs sensing and how to properly wire a power supply to a load. Calibrating certain sensing circuits, such as those used in electric vehicles (EVs), is critical to get right. An inaccurate calibration of an automotive battery monitoring circuit could, for example, allow […]
