Electrogastrogram (EGG) is refered to as recording a complex electro - oscillation in this paper. It is composed of many simple electro-oscillations of different frequencies and amplitudes. Suppose that oscillation curve have n + 1 extremum points with the coordinates (t1,v1). Where t1 is time, V1 is voltage value at the time t1. Thus, there are average half period T/2 and average amplitude V: Two parameteres F and A are defined as complesity degree of EGG. The physilogical & pathological informations are contained in these physical quanti...
