Enter a header (in row 3) for your new column (for example, “Local NYC Tax”) and input the rates for applicable employees. It is, IMHO, important to report intermodulation and noise separately, as the intermodulation result, although lost in the noise at lower signal levels, will increase rapidly, and the reporting of actual intermodulation dynamic range and intercept point (IP3) allows some extrapolation between the intermodulation at the noise floor and the. Third order distortions are the result of third order non-linearity and are formed by two mixing operations such as (A)+ (A)+ (A) or 3A, (A)+ (A)+ (B), 2A+B, A+B+C.
