The research of the synchronous detector of the phase-shift keyed signals in the system UDF MAOPCs

The paper presents analysis of work of a quadrature demodulator. In the environment of the system UDF MAOPCs (Multivariate Analysis and Optimization of the Parametric Circuits) was analyzed the influence of parameters of input signals and parameters of the synchronous detector on the output signals of the in-phase channel. On the example of the synchronous detector is shown that application of the frequency symbolic method makes it possible to in an explicit form determine the effect of selected parameters of the circuit elements on the characteristics of functional units of telecommunications equipment.
