In signal processing, cross-correlation is a measure of similarity of two series as a function of the displacement of one relative to the other. This is also known as a sliding dot product or sliding inner-product. It is commonly used for searching a long signal for a shorter, known feature. It has applications in pattern … Ver mais For continuous functions $${\displaystyle f}$$ and $${\displaystyle g}$$, the cross-correlation is defined as: If $${\displaystyle f}$$ and $${\displaystyle g}$$ are both continuous periodic functions of period Ver mais In time series analysis and statistics, the cross-correlation of a pair of random process is the correlation between values of the processes at different times, as a function of the two times. Let $${\displaystyle (X_{t},Y_{t})}$$ be a pair of random processes, … Ver mais Caution must be applied when using cross correlation for nonlinear systems. In certain circumstances, which depend on the properties of the input, cross correlation between the input and output of a system with nonlinear dynamics can be completely blind to … Ver mais • Cross Correlation from Mathworld • • Ver mais Cross-correlations are useful for determining the time delay between two signals, e.g., for determining time delays for the propagation of acoustic signals across a microphone array.
