Abstract
Correlation between a pair of digital signal segments is measured by apparatus including a plurality of multipliers. 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 are coupled to a summer, while each respective one of the multipliers is coupled to the input of a respective one of the D/A converts. The summer produces an analog output signal equal to the sum of the analog output signals produced by the plurality of D/A converter.
