    Abstract: The present invention concerns a method and an apparatus for detecting the presence of multipath propagation in a modulated digital signal (s(n),s(n) c ). A feature of the method is that of providing at least one first value (Ωc) of channel frequency, representative of said modulated digital signal free of multipath propagation, providing at least one second value of said channel frequency, representative of said modulated digital signal (s(n),s(n) c ) with multipath propagation, and comparing said at least one first value (Ωc) with said at least one second value so as to detect the presence of multipath propagation in said modulated digital signal (s(n)). Said second value of said channel frequency, representative of said modulated digital signal with multipath propagation being calculated by the use of the Teager-Kaiser operator.

    Abstract: The present invention concerns a method and an apparatus for identifying and suppressing shot or spike noise in a broadcast signal.
    A feature of the noise identification method in a modulated digital signal (s(n)) is that of applying a non-linear Teager-Kaiser function (Ψ) to said noise-corrupted modulated digital signal (s(n)) so to generate a first signal (s 1 Ψ(n), s 3 Ψ(n)) having a first component (s 1 Ψ(n) 1 , s 3 Ψ(n) 1 ), representative of the energy content (Θ s ) of said noise-corrupted modulated digital signal (s(n)), and a second component (s 1 Ψ(n) 2 , s 3 Ψ(n) 2 ) able to identify a time instant (T=t h ±i) in which there is spike noise in said noise-corrupted digital signal (s(n)).

    Abstract: The invention comprises an interface for translating data of different voltages. It includes an input terminal (52) structured to accept an input from a circuit supplied by a power supply having a first voltage level, as well as an output terminal structured to provide an output from the interface. A first circuit portion is powered by a power supply having the first voltage level (SUPPLYLOW). A second circuit portion is powered by a power supply having a second voltage level (SUPPLYHIGH). The invention advantageously comprises a power supply detection circuit (M20, M21) structured to accept a detection signal (VCCOFF). This detection circuit is coupled to the first and second circuit portions and structured to maintain a correct output at the output terminal (62) even after the power supply having the first voltage level (SUPPLYLOW) no longer supplies the first voltage level to the interface.
