Using measurements of anomalies in the Earth’s magnetic field and machine learning to extract data from raw signals, then matching them to accurate magnetic-anomaly maps, it may possible to navigate aircraft with reasonable accuracy ...

Decibels are commonly used in electronic systems that include RF, audio, and more recently, signal integrity. While many engineers already think in decibels, if you mostly work in the time domain, you may not think the same way. Because much of my ...

Condition monitoring is one of today’s core challenges in the use of mechanical facilities and technical systems in which, for example, motors, generators, and gears are used. Planned maintenance is becoming more and more important for ...

Abstract Measuring the signals from extremely high impedance sensors is a difficult task. These sensors can have output impedances in the Teraohms (1×10 12 Ω). The tiny signal currents coming from sensors such as Faraday cups and ...

Richtek Technology With huge choice of LED lamps available nowadays, it is not always easy to select the best suitable lamp for your living room or workspace. The light quality of LED lamps can vary greatly depending on the lamp design topology and ...

For a wide variety of products, manufacturing processes require highly precise and reliable temperature measurement technologies. Temperature is often measured through direct contact with a sensor, for example, through immersion of a sensor in ...

Where there is power there is heat, and where there is heat there is often a need to sense temperature (the most widely sensed physical variable). What we call temperature is our measurement of a material’s thermal energy, and there are many ...

Analog Dialogue Question: How could I measure the light intensity of different light sources? Answer: Take a red, green, blue LED. Determination of the light intensity can be crucial, for example, if you want to design the lighting of a room, or in ...

An AC bridge circuit can be used to measure the unknown capacitance of a sensor, such as a relative humidity (RH) sensor. Some RH sensors have a transfer function of capacitance vs %RH. Usually the value of the capacitance change (∆C) from 0% to ...

Johnnie Hancock, Keysight Technologies Electronic Design A digital phosphor oscilloscope is also a digital storage oscilloscope, and the same can be true in reverse. So what exactly separates the two? DSO stands for digital storage oscilloscope. ...
