However, many of these methods still rely heavily on time-domain features, potentially overlooking valuable information contained in the frequency domain of these signals (Zhao et al., 2024). The ...

Where X conv ∈ ℝ C × T × D 1 3 + D 2 3 + D 3 3 represents the stacked frequency domain features. W a t t ∈ ℝ C × T × 1 denotes the channel attention weight matrix, and X M F F ∈ ℝ C × T represents the ...

In this paper, we study the problem of demixing an observed signal, which is the summation of a set of signals that live on a multi-layer graph, by proposing several methods to decompose the observed ...

Analog circuit design is increasingly encountering mixed-signal circuits, and analog engineers need some understanding of discrete-time sampling circuits, whether they are sample-and-hold circuits or ...

Anytime the frequency spectrum of a signal is altered, its time domain performance will be altered too. Consider the spectrum of the 1-GHz square wave of Figure 1d.
