Correlation between a pair of digital signal segments is measured by apparatus including a pluraltiy of multipliers (1200). Each of the multipliers produces the product of a respective sample of each one of the signal segments. The outputs of a plurality of digital-to-analog (D/A) converters (1300) are coupled to a summer (80), while each respective one of the multipliers (1200) is coupled to the input of a respective one of the D/A converters (1300). The summer (80) produces an analog output signal equal to the sum of the analog output signals produced by the plurality of D/A converter.
On mesure la corrélation entre deux segments de signal numérique à l'aide d'un appareil comprenant plusieurs multiplicateurs (1200). Chaque multiplicateur génère le produit d'un échantillon respectif de chacun des segments de signal. Les sorties de plusieurs convertisseurs numériques/analogiques (N/A) (1300) sont couplées à un additionneur (80); chaque multiplicateur (1200) respectif étant couplé à l'entrée respective d'un des convertisseurs N/A (1300). L'additionneur (80) produit un signal de sortie analogique égal à la somme des signaux de sortie analogique produits par la pluralité de convertisseurs N/A.
