Abstract: This paper proposes and demonstrates an arbitrarily tunable multi-frequency pulse modulation scheme based on an active fiber loop, which effectively suppresses the interference fading effect ...

Reports from the city’s police and fire departments show that Renee Good, who was killed by an ICE agent last week, was found with two gunshot wounds to her chest and one to her forearm. A memorial on ...

The author is president of StreamS/Modulation Index LLC. This is one in a series about trends and best practices in streaming for radio stations. Greg Ogonowski The tables have turned, and we don’t ...

Abstract: This presents a low-power, high-data-rate impulse-radio ultra-wideband (IR-UWB) transmitter that integrates a two-dimensional differential pulse position modulation (2D-DPPM) with ...

Sometimes, when an audio component dies, the root cause is something electrical. Other times, the issue instead ends up being fundamentally mechanical. Delta sigma modulation-based digital-to-analog ...

Add a description, image, and links to the shellcode-encoder topic page so that developers can more easily learn about it.

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

ABSTRACT: This study introduces a Hybrid Bimodal Model for Analog-to-Digital (ADC) and Digital-to-Analog (DAC) signal conversions, addressing limitations of traditional systems, such as inefficiencies ...
