A comparison between two measures of convergence inrecursive-window based spectrum estimation
It is shown that approximations of the infinite impulse response (IIR) of a single-pole filter by a rectangular finite impulse response (FIR) through either the effective window length approach or the least squares inverse filtering approach yield the same results. Both the least squares inverse fil...
