Figure 5.
a) Representation of pulses of the normalized single channel current as the subtraction of two unit step functions. gi(t) is the normalized single channel current, and oj(t) and cj(t) are unit step functions at the opening and closing events respectively.
b) Representation of summation of normalized single channel currents as a difference of summations of unit steps functions at opening and closing events. G(t) is the summation of all gi(t), and O(t) and C(t) are the summation of all oj(t) and cj(t) respectively.
