•
Power voltage is dc 3 V and fed with regulated dc power
supply from battery terminal.
•
Voltages and waveforms are dc with respect to ground un-
der no-signal conditions.

•
Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production
tolerances.
•
Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
