Summary:
We apply sequential symbolic analysis to the first range difference (‘derivative’) of signal. We encode it using two-elements alphabet - symbol ‘1’ when the signal is growing or remains unchanged and symbol ‘0’ when the signal is decreasing. After such symbolization sequences of the same symbol (‘1’ or ‘0’) give us information for how long periods the signal is monotonous (growing or decreasing) and indexes characterizing distributions turn out to be good characteristics of the analyzed signal.
