The calculation of interaural time difference (ITD) is often modeled as a cross correlation.
(a) (a) Re-write the cross-correlation equation in terms of ITD. Designate the signal to the left and right ears as l(t) and r(t) respectively.
(b) I(b) In the equation, what operation is roughly analogous to coincidence detection? Explain your answer in less than 50 words.
(c) (c) What operation is analogous to the delay lines? Explain your answers in less than 50 words.
