Third-order intermodulation

WebTwo-tone third-order intermodulation distortion . Two-tone, third-order intermodulation distortion takes place when two RF signals simultaneously enter the mixer RF port and interact. In practice, this could occur in a multiple-carrier signal environment, or when an undesired signal interferes with a desired one. Of concern is the extent to ... WebApr 11, 2024 · Show, mathematically, why the slope of the line representing third-order intermodulation products increases at a rate that is three times faster than the fundamental tones when the system is approximated by v out = α 0 + α 1 v in + α 2 v in 2 + ⋯. Why are the odd-order intermodulation products of most interest?
