To avoid very large capacitors in a capacitively coupled isolation amplifier, the amplifier can use
A)modulation/demodulation
B)signal compression
C)a differential amplifier
D)dc coupling

Question

Quizplus · Accepted Answer

Modulation/demodulation techniques allow the signal to be transferred across the isolation barrier without the need for large capacitors. This is because the signal can be modulated to a higher frequency where smaller capacitors are effective for coupling.
