Answer:B
The presence of dirt or moisture degrades which of the following?
A. Circuit components B. High input impedance of buffer amplifier C. Low input impedance of buffer amplifier D. Low output impedance of buffer amplifier
Explanation: The presence of dirt or moisture degrades the high input impedance of buffer amplifier. Solder flux may also degrade it.
