A catalyst which purges a diesel engine exhaust gas of HC, CO, and SOF and reduces the emission of particulates as well and a method for the production thereof are provided. The catalyst for purifying a diesel engine exhaust gas has deposited on a refractory three-dimensional structure a catalyst component comprising silica-alumina supporting at least one noble metal selected from the group consisting of platinum, palladium, and rhodium and zeolite. This catalyst is produced by adding a noble metal component into a slurry of silica-alumina thereby inducing chemical adsorption, then adding zeolite to the resultant mixture thereby obtaining a mixed slurry of a noble metal-supporting silica-alumina and zeolite, dipping a refractory three-dimensional structure in the slurry thereby inducing deposition of the catalyst component, and subsequently calcining the resultant composite.

The present invention provides an apparatus and a method for precisely and adequately evaluating actual quality of reproduced data whenever applying a maximum likelihood decoder for converting signal reproduced from a recording medium into binary signal. Based on data arrays of a pair of binary data outputted from a “Viterbi” decoder, SAM values are secured by selecting any of path-metric differential values (00) and (11) being the difference between a pair of values compared when renewing path-metric values PMM (00) and (11) outputted from the “Viterbi” decoder. The minimum SAM value for an ideally-reproduced signal is outputted from a constant generating circuit. If the SAM values are verified as valid, and yet, if the SAM values coincide with the equation “input SAM values”≦“data value outputted from the constant generating circuit”, then squared values outputted from a square circuit are averaged by an averaging circuit. Finally, the average value is outputted as the reproduced signal evaluation.
