Random Signals,nd Poisson processes, are discussed in Sections 1.3 and 1.4. Mean-square calculus for random processes is presented in Section 1.5. Markov processes and renewal processes are discussed in Sections 1.6 and 1.7. The chapter concludes with bibliographical notes (Section 1.8).友好关系 发表于 2025-3-23 21:31:33

Spectral Analysis,ecorrelation time, frequency, and distances. In biomedical engineering, the spike- and wavelike form of the PSD indicates the period of epileptic seizure. In speech processing, spectral analysis is used to locate the formants of utterances of particular sound. In electronic warfare, the PSD is used to classify the targets.埋伏 发表于 2025-3-24 08:59:17
Random Signals,of random samples to the sampling of a random process. The characterization of a random process is given in terms of its time-dependent distribution and density functions. The characterization and classification is described in Section 1. 1. Two important characteristics of a random process from the图画文字 发表于 2025-3-24 12:01:10
Estimation, Optimization, and Detection,ospheric, optical, or electronic noise. The received signals may differ from the original signals in terms of amplitude, phase, frequency, timing or any combination because of the propagation medium, interference from other sources, and additive noise. Extraction of signals from the noise constitute易碎 发表于 2025-3-24 17:47:35
