摘要： The invention relates to the representation of digital signals. In order to improve the perception by a user of the quality of a digital signal, a first sample of first digital signal is approximated to a second sample of a second digital signal having a second number of significant bits lower than the first number of significant bits of the first sample. The second number of significant bits also depends upon the value of the first sample.

摘要： The invention relates to improved convolutions of digital signals. When a first digital signal is convoluted with a second digital signal to obtain an output digital signal, to be converted afterwards using a limited number of bits. In order to prevent a loss of information, and therefore a degradation of the output digital signal upon the future conversion, at least one of the first and the second digital signal is formed of suitable values that store the information from the first digital signal within the most significant bits of the output digital signal.

摘要： The invention relates to an electrodynamic transducer (1) having a dome membrane (2) comprising an electrodynamic motor with a coil (6) which is supported by a mandrel (3) that is solidly connected to the membrane which is suspended from a frame (7). The aforementioned coil is disposed in a gap in which it can move and which is defined at the centre by an inner magnetic structure (4) and at the periphery by an outer magnetic structure (5). According to the invention, the suspension does not contain a peripheral suspension nor an inner suspension. The inventive transducer comprises at least two means (11) for confining the magnetic field in the gap in order to form at least two tiered ferrofluidic seals (12, 13, 14) in the gap using a ferromagnetic liquid, such as at least to guide the coil and to form a pneumatic seal between the front and rear faces of the membrane, at least one of said ferrofluidic seals being continuous. The invention is suitable for loudspeakers.

摘要： The invention relates to the representation of digital signals. In order to improve the perception by a user of the quality of a digital signal, a first sample of first digital signal is approximated to a second sample of a second digital signal having a second number of significant bits lower than the first number of significant bits of the first sample. The second number of significant bits is also lower than a number of significant bits allowing the second digital signal, or a signal derived therefrom to match an expected bit depth of a processing unit said second digital signal, or a signal derived therefrom is to be sent to.
