SSB (single sideband) is a mode where the carrier and one sideband of the AM mode has been suppressed. Whether using USB (upper sideband) or LSB (lower sideband) more of the transmitter's signal is focused in the sideband used as compared to AM.
According to About.com, denier is not a type of nylon but a measure of the fineness of the fiber. One denier is equal to 1 gram per 9,000 meters of yarn. Manufacturers use the term denier with both natural and man-made fibers. Continue Reading.
Denier Measurement. The denier is obtained by weighing 9,000 meters of yarn or thread, expressing the result in grams. Thus the denier is a measure of linear density expressed in terms of grams per 9000 meters.Since a yarn with a higher denier has more mass per unit length than a yarn with a lower denier, it is thicker and tougher, provided that both yarns are made of the same kind of material.he fiber number multiplied by the number of fibers in a cross-section of the yarn equals the denier value of the yarn. Synthetic materials, such as polyester, may have fibers with fiber numbers less than one. The linear density of such fibers are measured in smaller units called microdeniers.
