The sine and cosine signals are examples of non-causal signal (see Figure-3).Important –All the anti-causal signals are non-causal signals but the converse is not true. Numerical Example Find which of the following signals are causal or anti-causal or non-causal − x(t)=e3tu(t−2)...

These models are widely used in nonlinear control, and more recently, in the study of communication over lossy channels. This paper considers a general jump linear estimation problem of estimating an unknown signal from an observed signal, where both signals are described as outputs of a jump ...

The propagation of limited-bandwidth signals, such as Gaussian wave packets, tuned to a transparent spectral region far below the resonance of an inverted two-level atomic medium, can be superluminal, i.e., with phase, group, and energy ... Chiao - 《Physical Review A Atomic Molecular & Op...
Enhancement of Periodic Signals: with Application to Speech Signals First, we propose several non-causal, time-domain filters for single-channel noise reduction. These non-causal filters can increase the noise reduction compared to their causal counterparts without increasing the distortion of the desire...
Substance use behaviours (SUB) including smoking, alcohol consumption, and coffee intake are associated with many health outcomes. However, whether the health effects of SUB are causal remains controversial, especially for alcohol consumption and coffee
Idling signatures of the resting brain have become a recent topic of interest in the functional MRI literature, wherein baseline activation signals are spa... RJ Gougelet 被引量: 0发表: 0年 Differentiating information transfer and causal effect The concepts of information transfer and causal effect...
(the corresponding colour for each variable is shown in the figure). The time series were down-sampled by a factor 1 to 10. For Factor 1, the time series were identical to the original signals. The down-sampling procedure destroyed the causal dynamics in both models and made causal ...
