Note 1) Measuring conditions are as listed in supplementary Table.Mesured with a current meter at test
point IA.
Note 2) Measureing conditions are as listed in supplemtary Tabke.Measured with a current meter at
test point IB.
Note 3) Decrease V30 gradually ,and measure the voltage when the waveform output is distorted.
The voltage is called VOL.
Next,increase V30 gradually,and measure the voltage when the top of waveform output is
distorted.The voltage is called VOH.
Voltage Vomax is calculated by the equation below:
Vomax = VOH-VOL
(V)
VOH
Note 4) Increase the input signal(SG2) amplitude gradually,starting from 700mVp-p.Measure the amplitude
of the input signal when the output signal starts becoming distorted.
Note 5) Input SG1,and read the amplitude output at OUT(29,32,35).The amplitude is called
VOUT(29,32,35).Maximum gain GV is calculated by the equation below:
GV=20Log(VOUT/0.7) (dB)
Note 6) Relative maximum gain GV is calculated by the equation bellow:
GV=VOUT(29)/VOUT(32),
VOUT(32)/VOUT(35),
VOUT(35)/VOUT(29)
Note 7) Measureing the amplitude output at OUT(29,32,35).The measuredvalue is called VOUT(29,32,35).
Main contrast control characterics VC1 is calculated by the equation bellow:
VC1=20Log(VOUT/0.7) (dB)
Note 8) Relative characteristics VC1 is calculated by the equation bellow:
VC1=VOUT(29)/VOUT(32),
VOUT(32)/VOUT(35),
VOUT(35)/VOUT(29)
Note 9) Measuring condition and procedure are the same as described in Note7.
Note 10) Measuring condition and procedure are the same as described in Note8.
Note 11) Measuring condition and procedure are the same as described in Note7.
Note 12) Measuring condition and procedure are the same as described in Note8.
