Webas a spectral analysis method. It should be noted at the outset that in the spectral estimation problem (of determin-istic or random data), the practical constraint is that one only has a nite data record, x(0);x(1);:::;x(N 1). It is from this record that one has to estimate the true spectrum, the so-called power spectral density.
