On July 22, 2025, Radio World republished one of my articles from October 25, 2011. The title was, “Rebuild That Relic of an AM Transmitter.” The idea of the article is to keep an old tube-type AM ...

Abstract: This paper presents a novel approach to Quadrature Amplitude Modulation (QAM) demodulation using neural networks, addressing the limitations of traditional demodulation techniques in complex ...

Communicating with someone thousands of miles away is now just a few keystrokes away, thanks to the internet and other forms of communication. Modern communication leverages a variety of wired and ...

Abstract: This article focuses on taking the STM32F407ZGT6 single-chip microcomputer and the four-channel DDS AD9959 as the core. Combined with the serial port screen, the modulation degree and ...

Oscillators ensure frequency stability in communication devices by generating precise reference signals, reducing drift, and enabling syncronization, modulation, and clarity. Oscillators are circuits ...

Commercial deployment of 6G communications systems is still not expected until the end of the decade, yet NTT Docomo has already been at the forefront of a string of developments moving towards the ...

Emerging, data-intensive technologies like artificial intelligence and machine learning are gaining popularity. Data centers, which act as the essential infrastructure for these technologies, need to ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...
