摘要： A Viterbi decoder for decoding a receive signal series encoded by an error correcting code is disclosed. The Viterbi decoder comprises a storage unit for storing a plurality of branch metrics, and a control unit for performing, upon receipt of the receive signal series, the processing of selecting a surviving path for each status using the branch metrics stored in the storage unit. The memory is prepared in accordance with the pattern of the receive signal series for storing a plurality of tables holding the branch metrics corresponding to each status. Each table holds the branch metrics in such a manner that the branch metrics of the two branches entering each status may be read by the control unit in the order of the branches constituting a trellis.

摘要： A method and apparatus for interframe predictive video coding and decoding which avoid the accumulation of rounding errors and thus obtain high-quality reproduced pictures. A frame memory outputs at least one reference picture to a prediction picture calculation unit, according to motion vector information with half-pel accuracy. From the reference picture(s), the prediction picture calculation unit produces a prediction picture by performing interpolation operations if the motion vector has a half-pel component. Here, each interpolated pel value is rounded off to an integer according to a particular rounding algorithm specified by a calculation controller. More specifically, the prediction picture calculation unit supports a first algorithm that rounds off the pel values toward positive infinity and a second algorithm that rounds off them toward negative infinity. The calculation controller outputs a rounding control signal that directs the prediction picture calculation unit to select either of those two algorithms with substantially equal probabilities of occurrence.

摘要： When a welding voltage is lowered, a pulse period is shortened or a peak current is reduced so that an average of a pulse frequency is not changed. Therefore, short circuit is regularly generated and a quantity of generated spatter is reduced. When the welding voltage is changed immediately before a melting drop separates from a tip of a wire, separation of the melting drop is predicted and the pulse period is ended. Due to the foregoing, a melting drop is regularly shifted at each pulse, and a quantity of generated spatter is reduced.
摘要翻译：当焊接电压降低时，脉冲周期缩短或峰值电流减小，使得脉冲频率的平均值不变。因此，定期产生短路，并且减少产生的飞溅量。当焊接电压在熔滴从电线的顶端分离之前立即改变时，预测熔滴的分离并且脉冲周期结束。由于上述原因，在每个脉冲下定期地移动熔融液滴，并且所产生的溅射量减少。

摘要： A received signal is output to an echo path and, at the same time, it is divided into a plurality of subbands to generate subband received signals, which are applied to estimated echo paths in the respective subbands to produce echo replicas. The echo having propagated over the echo path is divided into a plurality of subbands to generate subband echoes, from which the corresponding echo replicas are subtracted to produce misalignment signals. Based on the subband received signal in each subband and the misalignment signal corresponding thereto, a coefficient to be provided to each estimated echo path is adjusted by a projection or ES projection algorithm.

摘要： In a subband acoustic echo canceller which generates an echo replica from a subband received signal x.sub.k (m) by an estimated echo path in each subband, subtracts the echo replica from a subband echo signal y.sub.k (m) by a subtractor to generate a subband error signal e.sub.k (m) and uses an adaptive algorithm in an echo path estimation part to estimate the transfer function of the estimated echo path from the subband error signal e.sub.k (m) and the subband received signal x.sub.k (m) so that the subband error signal e.sub.k (m) approaches zero, the stop-band attenuation of each band-pass filter of a received signal subband analysis part for generating the subband received signal x.sub.k (m) is set to be smaller than the stop-band attenuation of each band-pass filter of an echo subband analysis part for generating the subband echo signal Y.sub.k (m) to thereby flatten the frequency characteristics of the subband received signals relative to the subband echo signals.
