This paper proposes the implementation of digit-serial Canonical Signed-Digit (CSD) coefficient FIR filters which can be used as format conversion filters in place of the ones employed for the MPEG2 TM5 (test model 5). A canonical digit representation of signed numbers is used to reduce the complexities in multiply operations. Practical design guidelines of digit-serial CSD FIR filter are provi...

This paper presents a novel eld-programmable gate array logic block architecture which incorporates support for digit-serial DSP architectures on a digit wide basis, without diminishing the support for random and control logic applications. To eeciently realize a digit-serial DSP design on FPGAs, one must create an FPGA architecture optimized for those types of systems. Key to the suitability o...

Males and females generally have different finger proportions. In males, digit 2 is shorter than digit 4, but in females digit 2 is the same length or longer than digit 4. The second- to fourth-digit (2D:4D) ratio correlates with numerous sexually dimorphic behavioral and physiological conditions. Although correlational studies suggest that digit ratios reflect prenatal exposure to androgen, th...

The role of intra-industry trade has been emphasized in international commerce since the 1960s. Innovation and government size, which affect goods and services production and government presence in international commerce, have also been highlighted since then. This study examines the influence of these two factors on international trade and estimates their effects in linear and logistic transfo...

Can the meaning of two-digit Arabic numbers be accessed independently of their verbal-phonological representations? To answer this question we explored the number processing of ZN, an aphasic patient with a syntactic deficit in digit-to-verbal transcoding, who could hardly read aloud two-digit numbers, but could read them as single digits ("four, two"). Neuropsychological examination showed tha...
