Method of detecting the correlation between signals with weighting |
摘要 |
A correlation detecting method in which in order to detect the correlation between a pair of electrical signal trains which should effect a correlation operation, the operation is effected while the relative position of the signal trains is shifted and during the operation, the signal levels of at least the opposite ends of each signal train are reduced relative to the signals at a central position of the signal train, thereby mitigating the correlation error attributable to the signals near the ends of the signal trains.
