The present work describes in detail the development and construction of an active bass reproduction system "subwoofer". For this, it uses a TPA3255 integrated circuit. This class D amplifier has two outputs that are applied ...

This paper proposes the development of a high-performance audio amplifier with global feedback. The proposed topology is based on "A design methodology for audio amplifiers with no global negative feedback: proposal and ...

This work analyzes and assembles the 50W "Blameless" audio amplifier designed by Douglas Self in his book. The three stages of the amplifier, the feedback loop, and the mechanisms used to minimize distortion were studied. ...

Satellite images are used in several areas, such as agribusiness, urban planning, environmental monitoring, among others. These images have a large and complex amount of data and the application of Machine Learning techniques ...

This article aims to develop a data acquisition board to identify the uphill and downhill stretches of a vehicle through an LSTM (Long Short Term Memory) artificial neural network, and to estimate the reduction in fuel ...

In this study, the application of neural network and machine learning techniques was explored in order to identify the presence of lesions related to diabetic retinopathy (DR) in fundus images. DR is a frequent complication ...

In this monograph, a high fidelity audio amplifier with tone control for headphones was developed. Circuits are built on printed circuit boards using discrete components. Topologies were initially determined to be simulated ...

This article describes the creation of an introductory video course on the LTspice circuit simulation software, with a focus on meeting the learning needs of students and electronics enthusiasts. The course comprises eleven ...

This work proposes the development of an audio amplifier without global feedback using bipolar transistors of junction. It will be used as the basis of the article “A design methodology for audio amplifiers without global ...

The Internet of Things (IoT) can play an essential role in helping to face the challenges of capacity and high demand in essential service locations (bank branches, postal logistics spaces, lottery shops, public offices, ...
