Can some one help me understand how to find the equivalent resistance int this circuit? The constant current source is confusing me because I know it supposed to have an endless resistance A and B ...

Electrical Engineering and Systems Science > Signal Processing Title:Chasing Lightning: Detecting, Characterizing, and Identifying a Powerful Space-Based GNSS Interference Source View PDF HTML (experimental)Abstract:This paper analyzes and identifies a space-based Global Navigation Satellite System (GNSS) interference source that has caused scores of powerful transient wide-area interference even…

The sentence is from The Art of Electronics third edition: To minimize the attenuation of a signal source below its open-circuit voltage, keep the load resistance large compared with the output ...

GPSDO Architecture Explained: How GPS Disciplined Oscillators Achieve Nanosecond Timing Introduction GPS Disciplined Oscillators (GPSDOs) are essential in various applications that require precise and stable time and frequency references. These oscillators use signals from the Global Positioning System (GPS) to discipline their internal oscillators, ensuring that they maintain a high degree of ac…

Electrical engineers and mathematicians develop and test a smartwatch that tracks electrical properties of pulsating blood

I try to make simple mic amplifier stage using lm358, from which the signal goes to a BJT amplifier. The output of amplifier is very low (only) with microphone stage, so i try to add lm358 op-amp ...

To quickly learn the complex operational patterns of thermal power generating units, this paper proposes an online monitoring method based on extreme learning machine (ELM) and SCADA data. First, health data from normal operations of the thermal power generating set are collected, and outliers unrelated to the unit’s operating conditions are removed from the SCADA data, along with local abnormal …

Modular multilevel high-voltage inverters are core components of rail vehicle traction systems, and their control performance directly determines the energy efficiency and operational reliability of traction drives. The primary objective of this study is to overcome the inherent limitations of traditional voltage model flux observers—specifically waveform distortion and DC component interference—…

I'm trying to recreate a soundcard from scratch for a PC8801FH (Old Japanese computer) and I'm largely done. However I can not figure out how to control the volume going to the stereo headphone out of ...

I am trying to understand which of the two (buck or boost) in general more/less noisy. For example I've got a buck converter with Vin=16,8 V and Vout=4,5 V and a boost converter with Vin=4,2 V and ...

I am trying to fully understand the physics behind transformer inrush current. I know that both toroidal and EI core transformers experience an initial current spike when connected to the AC grid, but ...
