microphonism मीनिंग इन हिंदी

Microwave tube designers used to take numerous steps to reduce microphonism in klystrons.
Where tuning was essential, a compromise usually was made between the resistance of the klystron to microphonism and the obtainable performance.
The usual test for microphonism in electron tubes is to tap the tube with a finger, light mallet, or small rubber ball while working as amplifier or oscillator.
