(7 points) Complete the following statements: a) List the three features required by any migration code b) If the following Figure shows the amplitude spectrum of a trace that has 2000 samples with 2ms time sample interval; the peak frequency is ....... Hz and the frequency sample interval is ........ Hz. c) If we migrated a dipping reflector segment CD to CD, where points C and D have offset (m) and time (sec) coordinates (750,1.2) and (850,1.4), respectively using a constant velocity of 3200m/s, then the coordinates of C and D will be and d) A simple harmonic motion is fully described in frequency domain by its and difference. e) can be used to test the similarities between two time signals. f) A wavelet is a wavelet with most of the energy concentrated at the end of it. g) Convolution in the time domain is equivalent to in the frequency.
