Note 1: Measure the circuit current when no signal is present.
Note 2: Apply a sine wave of f = 1kHz to the input, and adjust the input
level so that the output distortion is 1%. At this time, set the out-
put voltage to the maximum output level of V
OM
[V
P-P
].
Note 3: Measure the output V
O
[V
P-P
] with a sine wave of f = 4.43MHz,
1V
P-P
applied to the input. Voltage gain G
V
is:
G
V
= 20 Log (V

) [dB]
Note 4: Measure the outputs V

7 and V
O
1 [V
P-P
] each with sine waves of
f = 7MHz, 1V
P-P
and f = 1MHz, 1V
P-P
applied to the input. Voltage
frequency G
F
is:
G
F
= 20 Log (V

) [dB]
Note 5: Measure the output V
O
[V
P-P
] with a sine wave of f = 4.43MHz,
1V
P-P
applied to the input. Interchannel crosstalk C
T
is:
C
T
= 20 Log (V

/ V
IN
) [dB]
Note 6: Measure the output V
O
[V
P-P
] with a sine wave of f = 4.43MHz,
1V
P-P
applied to the input. The muting attenuation M
T
is:
