Abstract

The theoretical analysis of influence of change nonlinearity of phase shift of a sounding signal on information parameters of the transformed signal is performed. Expressions for amplitude and an initial phase of the first harmonic in the spectrum of a difference current component flowing through a nonlinear element of a frequency transformer are obtained. Measuring errors of amplitude and an initial phase of the information signal are calculated for this case. Practical recommendations for designing homodyne frequency transformers are formulated.
