###PURPOSE###
# Same as in demo1, except here gapped decon comes before
# spiking decon.  Again, you are to assume that the decon
# parameters are estimated from the autocorrelation shown in
# frame two.  Also see demo1 for the comments on making the data.


# First make the synthetic data for the deconvolution demo.

# The autocorrelation shows that:
#       wavelet extends to about 30ms
#	first repetition ends at about 160ms
# this accords well with the actual 64ms reverberations and wavelet of 24ms
