LOW POWER PARALLEL CORRELATOR FOR MEASURING CORRELATION BETWEEN DIGITAL SIGNAL SEGMENTS
摘要
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.
