Investigation of optical packet routing performance of optical packet switch with optical digital/analogue-conversion-type header processor (wavelength label switch)

open access: yesElectronics Letters, 2003
The dynamic routing operation of optical packets by a novel optical router consisting of an optical digital-to-analogue-conversion-type header processor, an electrically-tunable laser, a semiconductor optical amplifier-based wavelength converter, and an arrayed-waveguide grating router, is reported. A binary header is converted to the single pulse with

A new blind image conversion complexity metric for intelligent CMOS image sensors

open access: yesIET Image Processing, 2021
Many algorithms have been developed for complementary metal–oxide–semiconductor (CMOS) image sensors to speed up analogue‐to‐digital (A‐to‐D) conversion of captured images.

Radio Over Fiber Downlink Design for Spatial Modulation and Multi-Set Space-Time Shift-Keying

open access: yesIEEE Access, 2018
Spatial modulation (SM) and multi-set space-time shift-keying (MS-STSK) are capable of striking a flexible design trade-off between the multiplexing and diversity gains attained.

Predictive ECG coding using linear time-invariant models [PDF]

open access: yesArchive of Oncology, 2004
Electrocardiogram (ECG) signal compression suffers of lack of standards for analogue-digital conversion. Results of this study have shown that 8 bits/sample, although frequently in use, does not satisfy quality criteria for medical doctors.

Measurement of definite integral product of two more signals using two-bit ADCs [PDF]

open access: yesZbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2012
This paper presents the two-bit stochastic converter theory of operation. This converter could be used for the precise measurement of the effective (root-mean-square) value of voltage, current, electric power or energy and thus, could be applicable to ...

A 10 MHz‐BW 85 dB‐SNDR 4th‐order sturdy MASH 2‐0 noise shaping SAR ADC with 2nd‐order gain‐error‐shaping technique

open access: yesElectronics Letters
The multi‐stage noise shaping (MASH) ΣΔ ADC has a good potential to achieve high‐order noise shaping (NS) and high resolution. However, it suffers from quantization noise leakage caused by the mismatch between the analogue NS filter and the digital ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

A bridged‐switch energy‐efficient switching scheme for SAR ADCs with 2× input range

open access: yesElectronics Letters
In recent years, successive approximation register (SAR) analogue‐to‐digital converters (ADCs) have been widely applied in Internet of Things (IoT) sensor devices.

A Simplified Method of Pure Time Delay Generation

open access: yesMeasurement + Control, 1978
A method of time delay generation is described that is not dependent on a Pade or similar approximation. It is shown that the use of a serial analogue to digital conversion technique known as Delta Modulation can result in a simple and low cost ...

Time‐interleaving design of error‐feedback sigma‐delta modulators with infinite impulse response noise transfer function

open access: yesIET Circuits, Devices and Systems, 2021
Transceivers built to modern communication standards tend to be as digital as possible, including the radio‐frequency stages. This forces the digital‐to‐analogue converters (DACs) in the transmitter section to have a large bandwidth.
