Abstract: An electrical cable includes a conductor assembly. The conductor assembly has a first conductor, a second conductor, and an insulator structure surrounding the first conductor and the second conductor. The first and second conductors carry differential signals. The insulator structure has an outer surface. The electrical cable includes a cable shield wrapped around the conductor assembly to form a longitudinal seam that extends a length of the electrical cable. The cable shield engages the outer surface of the insulator structure. The cable shield has a single shield layer as an overall shield covering for the conductor assembly. The cable shield does not include a sealing tape wrapped therearound.

Abstract: A probability model represented as the product of the probability distribution of a mismatch vector g (or clean speech x) with an observed value y as a factor and the probability distribution of a mismatch vector g (or clean speech x) with a confidence index ? for each band as a factor, executes MMSE estimation on the probability model, and estimates a clean speech estimated value x^. As a result, each band influences the result of MMSE estimation, with a degree of contribution in accordance with the level of its confidence. Further, the higher the S/N ratio of observation speech, the more the output value becomes shifted to the observed value. As a result, the output of a front-end is optimized.
