Spectral density of Barkhusen noise in FINEMET-type materials

Stress level in Finemet materials studied by impedanciometry

Modelling of Sound Spectral Properties in Noise Suppression Engineering Materials

A modern way of life has also brought the problem of noise and its impact on both human health and the quality of life in general. There is an act in the Republic of Croatia that stipulates the permitted noise emissions for specific areas, but it also sets out that every bigger city should try to avoid hazardous noise. When it comes to traffic, there are several noise sources and methods to dec...

morphology, geochemistry, mineralogy, and micromorphology of soils of hormozgan province in relation to parent materials

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...

ACCURATE MEASUREMENTS Of SPECTRAL DENSITY OF PHASE NOISE IN DEVICES

Systematic errors larger than 10 dB can occur in the measurement of the spectral density of phase unless considerable caution is exercised. Some potential problems due to the shape of the analyzer passband and the Fourier frequency dependence of mixers are discussed. Three measurement systems are analyzed to determine the conditions under which they may be used to make spectral density measurem...
