Abstract	Some devices and systems for high-responsible management of technological processes require high stability of generated frequency. It is particularly important for the cases when the heterogeneous method is used, i.e. receiving an electrical signal with frequency of difference (/spl Delta/f= 6-12Hz). The principle of using the industrial frequency of 50Hz and its harmonic frequencies (nf/sub 50/ or (n-1)f/sub 50/) and the transformation of the frequency of 50Hz to receive low frequency between 10-30 Hz has been accepted. With using these two frequencies to receive combined signals, the variation of the industrial frequency has been eliminated and stable combined frequencies have been preserved. A principal scheme has been developed and research for determination of the actual frequency of the output signal with changing its elements parameters has been carried out. The purpose of this paper is to model an electronic scheme, built up on the base of transformation of the industrial frequency of 50 Hz.
