摘要： The invention is relating to an arrangement for annealing a strip (1) with direct resistance heating comprising at least two rotable supported rollers (2, 7; 8, 9; 12, 13; 17, 18, 19), where at least one of said rollers (2; 8, 9; 12, 13; 17, 18) is having a plurality of electrically conductive segments (5) at the circumference of the said roller (2; 8, 9; 12, 13; 17, 18), which segments (5) are insulated from each other and where the electric current is conducted simultaneously to only a part of said electrically conductive segments (5) by at least one sliding contact (3, 4; 10, 11; 14, 15, 16) so that the electric contact to the segment (5) is made after the mechanical contact of the strip (1) and the electrical contact being disconnected from the segment (5) before the mechanical contact is disconnected. It is also relating to a method for annealing a strip (1).

摘要： A digital resampling system is provided for converting a first digital signal to a second digital signal, where both signals represent the same analog signal but sampled at two different clock rates which are not phase-locked together. A filter is clocked by the first clock and outputs filtered samples at the first clock rate, optionally omitting samples which will not be used. A phase indicator determines the relative phase position of the first and second clocks and indicates an integer phase value and a fractional phase value which together indicate where a tick of the second clock falls among the ticks of the first clock. The integer phase value identifies a clock cycle of the first clock in which a tick of the second clock occurs, and the fractional phase value represents a fraction identifying a position of the tick of the second clock within the clock cycle of the first clock. A sample selector selects M filtered samples from those provided by the non-decimating filter based on the integer phase value. A weight generator generates M weights based on the fractional phase value, and a weight averager weights the M filtered samples by the M weights, and outputs a sum or an average of the weighted samples. The resampler is applicable to digital-to-digital resampling, as well as resampling in an analog-to-digital or digital-to-analog conversion system.
