ABSTRACT
An algebraic technique which computes nonlinear, delay-free dig-
ital filter networks is applied to model the Dolby B in the discrete-
time. The model preserves the topology of the analog system,
and imports the characteristics of the nonlinear processing blocks
which are responsible of the peculiar functioning of Dolby B. The
