• All voltages are in V.
• Voltage is DC with respect to ground unless otherwise
noted.
• Readings are taken with a 10M
Ω digital multimeter.
• Readings are taken with a color-bar signal input.
• Voltage variations may be noted due to normal produc-
tion tolerance.
• Circled numbers are waveform references.
