Black Side Gamma Measurement Method
Measure the output voltages y
1
to y
10
which correspond to the input voltages a
1
to a
10
using SG8 as the input
signal. (Measure the voltage from the reference level. Label the white side from the reference level as positive,
and the black side as negative.)
Select the two points where | y
n
– y
n – 1
| (n = 2 to 10) is a maximum, and label these points y
k
and y
k – 1
. Also,
label the input voltages which correspond to y
k
and y
k – 1
as a
k
and a
k – 1
, respectively.
Next, measure the output voltages y
1
to y
10
which correspond to the input voltages a
1
to a
10
using SG9 as the
input signal.
Select the two points where | y
n
– y
n – 1
| (n = 2 to 10) is a maximum, and label these points y
h
and y
h – 1
. Also,
label the input voltages which correspond to y
h
and y
h – 1
as a
h
and a
h – 1
, respectively.
From the above:
Maximum gain GM = (y
k
– y
k – 1
)/(a
k
– a
k – 1
)
Minimum gain GN = (y
h
– y
h – 1
)/(a
h
– a
h – 1
)
The black side gamma gain is defined as the ratio of the maximum gain to the minimum gain. In other words:
Gamma gain = 20 log (GM/GN)
The gamma breakpoint is defined as the intersection between the straight line passing through points (a
k
, y
k
)
and (a
k – 1
, y
k – 1
) and the straight line passing through points (a
h
, y
h
) and (a
h – 1
, y
h – 1
). In other words:
Gamma breakpoint = (GM
GN
(a
k
– a
h
) – GN
y
k
+ GM
y
h
)/(GM – GN)
