Which mechanism allows decoupling amplifier stages using capacitance?

A)Capacitive reactance impeding low frequencies
B)Inductive kickback cancelling spurious currents
C)Dielectric absorption blocking high frequencies
D)Electrostatic discharge neutralizing amplifier input

💡 Explanation

Capacitive decoupling relies on capacitive reactance because it presents high impedance to DC signals and low impedance to AC signals. Therefore, AC signals pass, while DC bias is blocked, rather than both signals passing or being blocked under different constraints.
