The low frequency and high frequency fall in the gain of an RC-coupled amplifier respectively is due to
1
Increase in the reactance of bypass capacitance and coupling capacitance
2
Decrease in the reactance of coupling capacitance and bypass capacitance
3
Increase in the reactance of coupling capacitance and decrease in the reactance of bypass capacitance
4
Increase in the reactance of bypass capacitance and decrease in the reactance of coupling capacitance
