FIELD: pulse and measurement technology. SUBSTANCE: two-phase harmonic-signal generator has control sawtooth-voltage generator 1, pulse shapers 2,3, inverter 4, reversing counter 5, read-only storage units 6,7, multiplying digital-to-analog converters 8,9, digital-to-analog converters 10,11, adders 12,13, low-frequency filters 14,15. Linearly varying signals of amplitudes determined by current values of cosine and sine functions, respectively, are shaped across outputs of multiplying digital-to-analog converters 8,9. EFFECT: reduced nonlinear distortions due to improved accuracy of piecewise-linear approximation of input signals in quadrature. 3 dwg
