Abstract: For multistage noise-shaping (MASH) delta-sigma modulation, this paper presents a new structure that is free of spurs for all input values. The proposed MASH structure cascades several first ...
Adult hippocampal neurogenesis (AHN) supports learning, memory, and emotional regulation, and is regulated by intrinsic and extrinsic factors. Dopamine influences neurogenesis in animal models, but ...
Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...
The continuous evolution of coronaviruses poses persistent and severe threats to both human and animal health. While α- and β-coronaviruses mainly infect mammals, including humans, γ-coronaviruses ...
Abstract: The fact that VCO-ADCs produce noise-shaped quantization noise suggests that a link between frequency modulation and Sigma-Delta modulation should exist. The connection between a VCO-ADC and ...
This Letter proposes a high-security and high-order signal transmission method that is based on delta-sigma modulation (DSM) and discrete memristive-enhanced chaos (DMEC). We employ the DMEC for the ...
This file type includes high resolution graphics and schematics. Delta-sigma analog-to-digital converters (ADCs) are fascinating—almost mythical in their ability to support low- to medium-speed and ...
In this paper, we will attempt to explain sigma delta converters with a non-mathematical approach, covering the basic concepts of noise shaping and oversampling, explained with the help of some ...
Pulse density modulation is just the analog portion of a delta-sigma analog-to-digital converter (ADC). It coverts an analog signal into a digital density stream. A recent online discussion about it ...
