TWO-PHASE HARMONIC SIGNAL GENERATOR Russian patent published in 2022 - IPC H03B27/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering, in particular, can be used to generate harmonic excitation signals (HSG) of sine and cosine windings of rotating transformers. The generator of two-phase harmonic signals provides an increased degree of symmetry of the half-waves of the output signals by connecting to the outputs of each first active low-pass filter of the corresponding RC circuit, which provides suppression of the DC component of the signals at the inputs of each second active low-pass filter, which increases the noise immunity of the generator. The use of a bus shaper provides an increase in noise immunity by amplifying the SIN and COS signals during transmission over communication lines and at the same time protects the outputs of the pulse sequence shaper from static voltage, which increases the reliability of the HSG.

EFFECT: increasing the noise immunity of the generator, as well as increasing the reliability of the generator due to protection against static electricity.
