5-3. SCHEMATIC DIAGRAM
Note:
• All capacitors are in µF unless otherwise noted.
• All electrolytic capacitors are rated at 50V unless otherwise
noted.
• All resistors are in ohms.
kΩ = 1000Ω, MΩ = 1000kΩ
• Indication of resistance which does not have rating electrical
power is as follows.
•
•
•
• All variable and adjustable resistors have characteristic curve
B unless otherwise noted.
• Redings are taken with a color-bar signal input.

• Readings are taken with a 10M digital m ultimeter.
• Voltage are dc with respect to ground unless otherwise
noted.
• Voltage variations may be noted due to normal produc-
tion tolerances.
• All voltage are in V.
•
• Circled numbers are waveform references.
