FIELD: physics.
SUBSTANCE: method includes, in conditions of varying geometrical dimensions and shapes of radiation sources, setting up a model as a reference coordinate system in rotation mode; synchronously on frequency and phase of the simulated rotation, generating two "unfolding-folding" signals of sine and cosine lines of a single trigonometric circle; comparing, on a first channel, the "unfolding-folding" signal of the sine line and, on a second channel, the "unfolding-folding" signal of the cosine line with a field of variable reference levels, wherein positions of the field of levels and the variable sampling interval are selected based on approach to the initial single sine-cosine functions using an approximation technique; and at points when the "unfolding-folding" signals of each level cross, generating quadrature reference signals in the form of a sequence of count pulses, which code the sine-cosine functions with a unitary pulse-number code in the form of a binary number, as well as in the form of a parallel additional binary code and in analogue form.
EFFECT: real-time simulation of both digital and analogue forms of quadrature reference signals.
