In this chapter, we first explain what we mean by a signal, and then we describe some characteristics such as energy, frequency, phase, power spectrum, etc. We show how to analyse it by the means of spectral analysis and Fourier transform. Moreover, as the Fourier transform does not provide any...

Key Features:This book covers the essence of wavelet analysis - such as the maximum overlap discrete wavelet transform, wavelet correlation, and variance - in a unified manner. It covers important topics in finance, such as portfolio asset allocation, asset pricing, hedging strategies, new risk...
