QUADRATURE HARMONIC SIGNAL GENERATOR Russian patent published in 2015 - IPC H03B27/00 

FIELD: radio engineering, communication.

SUBSTANCE: quadrature harmonic signal generator includes a harmonic signal source, two phase changers, two comparators, two univibrators, two sampling-storage devices, a divider, a multiplier, an adder, the output of which is connected to the second output of the quadrature harmonic signal generator, the first output of which is connected to the inputs of the first and second phase changers, two resistors, a capacitor, an operational amplifier and a scaling amplifier, wherein the harmonic signal source is connected between the input of the second phase changer and a common bus.

EFFECT: synchronising output signals with the phase of the input signal, the amplitude and frequency of which may vary in a wide range.
