Abstract :
It is shown that the digital lattice filter utilized as a predictor in speech processing is a special case of a broad class of filters with identical properties in which the delay element is replaced by an arbitrary analog or digital all-pass filter. The performance of three filters in this class, the delay element and single-pole analog and digital all-pass sections, are compared for the special estimation application.
