Abstract This is part 2 in a series of articles focusing on the properties and applications of convolutional neural networks (CNNs), which are mainly used for pattern recognition and the classification of objects. In the first article ...

Abstract The world of artificial intelligence (AI) is rapidly evolving, and AI is increasingly enabling applications that were previously unattainable or very difficult to implement. This series of articles explains convolutional neural networks ...

Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power loss and are available in either single coil or ...

As shown in Figure 1, this issue had been previously addressed during pre-internet times in EDN of January 18,1990 but a further detailed look at the idea is warranted thirty-four years later. Figure 1. Archival design idea “Resistor isolates ...

Large currents flowing in a length cable can be measured using the voltage drop along the cable. It eliminates the need for a bulky shunt or expensive magnetic measurement method. Accuracy is limited however because of the +0.39%/ C tempco ...

Many power-supply designs rely on accurately sensing the voltage across a current-sense element. Multiphase regulators use the sense voltage to force current sharing among phases, and single-phase regulators to control the current-limit setpoint. ...

75 years ago, one of the biggest electronics firms of the century got its start in a Palo Alto, California, garage and it did so with the help of Mickey Mouse. In the 1930s and 40s, David Packard and fellow Stanford University graduate William ...

This article describes a technique to compensate the DC voltage drift in the output of a directly-coupled AB-Class audio power amplifier. The main benefit of a directly-coupled output is improved bass response. Since the design eliminates the ...

A recent Design Idea ( Ref. 1 ) presents a circuit to measure an airflow rate up to 2000 fpm using two transistors in a Darlington configuration. One transistor works as a self-heated thermal sensor and the other one compensates for ambient ...

Brushless DC (BLDC) motors transform electrical power into mechanical power. However, there’s no such thing as a perfect motor; there are always losses in the transformation. The three main types of losses created during the conversion are ...
