Statistical Approach to Signal Analysisacteristics of the quantity and of the process that generates it, rather than in those of the particular sequence we measured. The measured record, affected by random errors, is interpreted as a segment of a persistent discrete-time random power signal, conceptually resulting from sampling a continu

Non-Parametric Spectral Methodslization of the underlying random process—one among the infinite sequences that the process can generate when we measure it. The simplest approach to spectral estimation, i.e., the periodogram, turns out to perform poorly: the variance of the estimate is high and does not decrease with increasing le

Parametric Spectral Methods is supposed to represent the persistence, i.e., autocorrelation, present in the process generating the observed signal. The signal’s spectral characteristics are then derived from the estimated model. This approach requires selecting model type and order (number of parameters), and then estimating

Discrete Wavelet Transform (DWT)nomy in the representation of the signal and possibility of perfect signal reconstruction (PR) are crucial. The simplest formulation of the DWT problem includes two types of basis functions for the expansion: the scaling and wavelet functions. We will see how an ideal, infinite-length but finite-ene

The Politics of ‘Women’s Place’ since 1975r be generated directly by inherently-discrete-time processes. Deterministic signals have a univocal mathematical description, so that future signal values are exactly predictable. Random signals do not allow for such a description: their treatment requires statistical tools since signal evolution c
