Even if the Fourier analysis dates back before the Fourier's work and even if the different Fourier analysis developments have been done after him, Fourier is an icon whose influence is fundamental still today. In 1822, Fourier1 in his work entitled "Analytical Theory of Heat", explained the...
The human perception of sound is a suitable area for the application of a simultaneous time-frequency analysis, since the ear is selective in both domains. A perfect reconstruction filter bank with bandwidths approximating the critical bands is presented. The orthogonality of the filter makes it po...

Therefore, we introduce XAI4EEG: an application-aware approach for an explainable and hybrid deep learning-based detection of seizures in multivariate EEG time series. In XAI4EEG, we combine deep learning models and domain knowledge on seizure detection, namely (a) frequency bands, (b) location...
Time-Frequency Displays The preceding chapters have been concerned with the spectrum analysis of sinusoids and noise at a particular point in time (or a single spectrum for all time). This chapter introduces the Short-Time Fourier Transform (STFT)--a time-ordered sequence of spectral estimates, ...
Analysis of performance and interference effects in Radio Frequency IDentification systems During the last years, the definition of "communication" has been rewritten by the viral diffusion of a class of devices which has been thought and created to open new and fast channels of interaction. The co...
The ANN in both stages use Levenberg-Marquardt algorithm [88] and feed-forward architecture [113] for training. In pre-processing, logarithmic operator is applied to stretch image over the entire frequency band, which otherwise is concentrated in the 0-2500 units only. It removes the need for...
Analysis of the performance of time-spread optical code-division multiple access systems with integrate-and-dump receivers (2) while the performance of both systems is improved as the optical sources become more incoherent, those with integrate-and-dump receivers benefit more,... SG Park,BD Choi...
