Turn SW
Input signal 1 (f = 4MHz, picture period amplitude = 0.5 V
Adjust the input amplitude so that the picture period amplitude of pin 13
is 2 V
Turn SW
Measure the picture period amplitude (V
Calculate by the following formula the amount of crosstalk from the
analog RGB to the video.
vA → AR = −20 × ℓog (v
