D) noise caused by using JFETs

Question

Quizplus · Accepted Answer

Cross modulation is a form of receiver noise that occurs when a non-linear or non-square law device (such as a diode or transistor operating in a non-linear region) mixes or modulates an undesired signal (like noise or another strong signal) onto the desired signal. This is due to the non-linear device's inability to maintain a constant amplification or detection characteristic across its operating range, leading to the modulation of one signal by another.
