How can an oscillator's microphonic responses be reduced?
Pick an answer to check it.
Answer: D. Mechanically isolate the oscillator circuitry from its enclosure
Microphonics come from mechanical vibration, so the fix is mechanical: isolate the oscillator circuitry from the enclosure. Electrical fixes like a cleaner power supply do not stop vibration.
Tip: Mechanical problem, mechanical fix.
