Further results in the noise-loading analysis of a memoryless nonlinearity characterized by a Taylor series of finite order

See also ibid., vol.IM-22, p.246-9 (1973). Provides an explicit expression for the noise power ratio (NPR) of the memoryless nonlinearity. This expression generalizes previously available results by allowing: wide-band signals; nonflat frequency-spectrum inputs; and nonrectangular notches. The NPR is expressed as a function of the `unnotched' input spectrum and the notch transfer function. Examples are presented to compare the theory with measurements.
