FIELD: electronic engineering, possible use for transformation of voltage from alternating to constant. ^ SUBSTANCE: during realization of method of sensitive phase-sensitive demodulation of signal of induction angle indicator, capacitor is charged by if signal of angle indicator during passage of spike value by the signal. Angle indicator is powered by sinusoidal voltage, received from external impulse signal, from which a net of frequencies is received. By addition of frequencies, time interval is created, during which capacitor is charged. Device for realization of method contains capacitor (8), buffer (9), quartz generator (10) of impulses, binary counter (11), generator (12) of sinusoidal voltage, induction indicator (13) of angle, circuit 5AND-NOT (14), analog key (15). ^ EFFECT: increased precision and interference resistance, ensured change of signal phase. ^ 2 cl, 4 dwg |
