What causes intermodulation in an electronic circuit?
Negative feedback
Lack of neutralization

Positive feedback
Բացատրություն
Intermodulation requires a nonlinear transfer characteristic: only when the output is not a straight-line function of the input do two input frequencies produce sum, difference and higher-order combination products. A perfectly linear circuit generates no new frequencies, regardless of feedback or neutralization.
