What causes intermodulation in an electronic circuit?
- A.Negative feedback
- B.Lack of neutralization
- C.Nonlinear circuits or devices (correct answer)
- D.Positive feedback
WhyIntermodulation in an electronic circuit is caused by nonlinear circuits or devices. Intermodulation arises from nonlinear circuits or devices, any component whose output isn't a simple, proportional scaling of its input will mix multiple input signals together and generate new sum-and-difference frequency products, answer C. Negative feedback, lack of neutralization, and positive feedback are related to amplifier stability and gain control, not the fundamental nonlinearity that actually produces intermodulation products.
