FIELD: radio engineering and communication.
SUBSTANCE: invention relates to the field of radio engineering, in particular can be used for generation of harmonic excitation signals of sine and cosine windings of rotating transformers. Two-phase harmonic signal generator comprises a flip-flop, an inverter, a pulsed sequence generator, first and second adders, first, second, third and fourth active low-pass filters of the second order, first and second power amplifiers, a current limiter unit.
EFFECT: technical result consists in improvement of reliability due to high degree of resistance to external factors, as well as providing identity of electrical characteristics of sine and cosine generator signals.
