Abstract:
An equalizing device comprising:a first and a second branch which are connected; an input via a signal separation device to separate the frequencies of an input signal for producing a signal that occupies a first frequency band via the first branch, and a signal that occupies a second frequency band via the second branch; and at output via a recombining device to produce an output signal which occupies the first and second frequency bands based on the signals transmitted over the first and the second branch; and wherein: the first and second frequency bands correspond to a cutting off of a useful frequency band between a low part and a high part; the first and second branches each include at least an attenuator, while the attenuation of the first attenuator is higher than that of the second attenuator; and the separation and recombining devices having a passband designed in such a way that the output signal SOUT has a substantially constant amplitude in said first and second frequency bands.
