The report makes use of the concept of nonlinear transfer functions of quasi-linear systems which is based on the application of the Volterra functional series to the analysis and modeling of communication receivers. In particular, this report makes use of the fact that certain high-order nonlinear effects are functions of first-order network functions at many different frequencies. When the nonlinear effects falls within the transmission band of a receiver and if the frequencies of certain first-order transfer functions to which these effects are related fall outside the transmission band, then it is possible to reduce these nonlinear effects by modifying the first-order transfer functions outside the band without altering the first-order transfer function inside the band. The basic principles are delineated and several examples are furnished.
