Lab. 4: Random Signals

21 abril 2015, 14:00 Bruno Guerreiro

In this Lab project we'll explore several concepts related to random signals, which account for most signals observed in nature, in society, and in economy. We will consider two signals in this work (Gaussian signals and speech signals) to explore the definitions, properties, and estimators for the mean, variance, and correlation function.
