FIELD: radio engineering, communication.
SUBSTANCE: the controllable quadrature signal generator contains four comparators, two univibrators, two sampling-storage devices, two dividers, two limiters, two multipliers, two operational amplifiers, the inverter, three adders, two resistors, two capacitors, RS trigger, the reference voltage source, while the second inputs of the first and second multipliers are connected to the control bus, the outputs of the first and second limiters are respectively the first and second outputs of the device.
EFFECT: improvement of spectral purity of the formed quadrature harmonic signals.
