On modelling and description of the output signal of a sampling device [PDF]
Archives of Electrical Engineering, 2023 The problem of an inconsistent description of an “interface” between the A/D converter and the digital signal processor that implements, for example, a digital filtering (described by a difference equation) – when a sequence of some hypothetical weighted

The Problem of Aliasing and Folding Effects in Spectrum of Sampled Signals in View of Information Theory [PDF]
International Journal of Electronics and Telecommunications, 2022 In this paper, the problem of aliasing and folding effects in spectrum of sampled signals in view of Information Theory is discussed. To this end, the information content of deterministic continuous time signals, which are continuous functions, is ...

Definition of Sampled Signal Spectrum and Shannon’s Proof of Reconstruction Formula [PDF]
TransNav, 2022 The objective of this paper is to show from another perspective that the definition of the spectrum of a sampled signal, which is used at present by researchers and engineers, is nothing else than an arbitrary choice for what is possibly not uniquely ...

Period and signal reconstruction from the curve of trains of samples
IET Signal Processing, 2022 A finite sequence of equidistant samples (a sample‐train) of a periodic signal can be identified with a point in a multidimensional space. Such a point depends on the signal, the sampling period, and the starting time of the sequence.

Multitemporal Sampling Module for Real-Time Human Activity Recognition
IEEE Access, 2022 Human activity recognition, which recognizes human activities from time-series signals collected by sensors, is an important task in human-centered intelligent systems such as in healthcare and smart vehicles. In these applications, rapid response of the

Design of a novel CEM‐FRM‐based low‐complexity channelised radar transmitter
IET Radar, Sonar & Navigation, 2021 With the development of the radar technology, it is required that a radar has wider bandwidth and can transmit multiple signals simultaneously. The polyphase digital channelised transmitter structure can transmit multiple signals simultaneously and ...

Transfer Learning for Event Detection From PMU Measurements With Scarce Labels
IEEE Access, 2021 Event detection in electrical grids is a challenging problem for machine learning methods due to spatiotemporally nonstationary systems and the inability to automate event labeling in high-volume data such as PMU measurements.

Spectrum Aliasing Does not Occur in Case of Ideal Signal Sampling [PDF]
International Journal of Electronics and Telecommunications, 2021 A new model of ideal signal sampling operation is developed in this paper. This model does not use the Dirac comb in an analytical description of sampled signals in the continuous time domain. Instead, it utilizes functions of a continuous time variable,
