Should {\Delta}{\Sigma} Modulators Used in AC Motor Drives be Adapted to the Mechanical Load of the Motor? [PDF]
, 2012 We consider the use of {\Delta}{\Sigma} modulators in ac motor drives, focusing on the many additional degrees of freedom that this option offers over Pulse Width Modulation (PWM). Following some recent results, we show that it is possible to fully adapt

Computationally efficient low-power sigma delta modulation-based image processing algorithm
Mehran University Research Journal of Engineering and Technology, 2023 Digital Image Processing has dominated Digital Signal Processing at the cost of more memory, resources, and high computational power. In image processing, filtering transformations and other operations need complex multiplications, and the multiplier is ...

Distributed multi-user MIMO transmission using real-time sigma-delta-over-fiber for next generation fronthaul interface [PDF]
, 2020 To achieve the massive device connectivity and high data rate demanded by 5G, wireless transmission with wider signal bandwidths and higher-order multiple-input multiple-output (MIMO) is inevitable. This work demonstrates a possible function split option

Colored-Gaussian Multiple Descriptions: Spectral and Time-Domain Forms [PDF]
, 2016 It is well known that Shannon's rate-distortion function (RDF) in the colored quadratic Gaussian (QG) case can be parametrized via a single Lagrangian variable (the "water level" in the reverse water filling solution).

A describing function study of saturated quantization and its application to the stability analysis of multi-bit sigma delta modulators [PDF]
, 2013 Just as their single-bit counterparts, multi-bit sigma delta modulators exhibit nonlinear behavior due to the presence of the quantizer in the loop. In the multi-bit case this is caused by the fact that any quantizer has a limited output range and hence ...
