Which outcome occurs when a local oscillator's frequency drifts in a homodyne receiver?

A)Signal fading increases noticeably
B)Image frequency interference occurs
C)Quadrature amplitude modulation ceases
D)Signal strength remains effectively constant

💡 Explanation

Signal fading increases because a homodyne receiver relies on the **carrier synchronization** mechanism. Therefore, drift misaligns the demodulation reference, reducing the signal amplitude. This degradation is more immediate rather than developing image frequencies, which is related to super heterodyning.
