Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

The design strategy for terahertz metasurfaces capable of achieving spin-selective functionality through complex-amplitude modulation is systematically categorized into four distinct parametric ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

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 ...

The proposed CORDIC-less digital polar transmitter demonstrates superior power added efficiency (PAE) and system efficiency (SE) for similar modulation signals. It also supports wider bandwidths, ...

Researchers at Skoltech have developed an ultra-compact electro-optic modulator based on silicon photonics and plasmonics ...

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 ...

This manuscript presents important findings that challenge traditional models of speech processing by demonstrating that theta-gamma phase-amplitude coupling in the auditory cortex is primarily a ...

Researchers led by Professor Ting Mei (Northwestern Polytechnical University) and Professors Xiaocong Yuan & Yuquan Zhang ...

Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and elevate data rates concurrently. This effectively aligns with the growing ...
