# This is an example tool that shows how to connect to ODR-DabMod's dpd TCP server
# and get samples from there.
#
# Since the TX and RX samples are not perfectly aligned, the tool has to align them properly,
# which is done in two steps: First on sample-level using a correlation, then with subsample
# accuracy using a FFT approach.
#
# It requires SciPy and matplotlib.
