Question

Can you explain me the function of bypass capacitor in an amplifier very cleary??

Answer 1

i think to stop the dc components!

Answer 2

we use capacitor in an amplifier!

Answer 3

or

Answer 4

To avoid an ac signal Voltage from being developed across the emitter resistor which would cause a reduction in the amplifier`s gain we use bypass capacitor in an amplifier in common emitter amplifier

Answer 5

this type of reduction of gain is so called degenerative feed back which can be removed by using bypass capacitor in an amplifier
