3-6. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
3-7. WAVEFORMS
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed
in each block.)
For schematic diagrams.
Note:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in
Ω
and
1

W or less unless otherwise
specified.
•
f
: internal component.
•
C
: panel designation.
For printed wiring boards.
Note:
•

• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
