THERSHOLD VOLTAGE AND SATURATION VOLTAGE
Vth:
The voltage Vop which the transmission rate of segment is 90%(positive) or 10%(negative) of saturated value on conditions
of the selected waveform.(non-selected waveform is opposition)
Vsat:
The voltage Vop which the transmission rate of segment is 10%(positive) or 10%(negative) of saturated value on
conditions of the selected waveform.(non-selected waveform is opposition)
