• Waveforms are taken with a oscilloscope.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions. Voltage variations may be noted due to normal produc-
tion tolerances.
no mark : MD PLAY
( ) : MD STOP • Circled numbers refer to waveforms.
• Signal path.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc- E : MD PLAY
