Time Delay Analysis
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. After calculating the cross-correlation between the two signals, the maximum (or minimum if the signals are negatively correlated) of the cross-correlation function indicates the point in time where the signals are best aligned, i.e. the time delay between the two signals is determined by the argument of the maximum, or arg max of the cross-correlation, as in

Famous quotes containing the words time, delay and/or analysis:
“O heavens! how short a time does it take to put an eternal end to a woman’s liberty!”
—Frances Burney (1752–1840)
“To achieve the larger goal of teaching her children consideration of others, a mother can tolerate some frustration of her own wishes, she can delay having what she wants, she can be flexible enough to compromise. And this is exactly what her child must also learn: that it is possible to survive frustration, it is possible to wait for what he wants, it is possible to compromise without capitulating.”
—Elaine Heffner (20th century)
“Whatever else American thinkers do, they psychologize, often brilliantly. The trouble is that psychology only takes us so far. The new interest in families has its merits, but it will have done us all a disservice if it turns us away from public issues to private matters. A vision of things that has no room for the inner life is bankrupt, but a psychology without social analysis or politics is both powerless and very lonely.”
—Joseph Featherstone (20th century)
