FUNCTIONAL QUADRATURE SIGNAL GENERATOR Russian patent published in 2016 - IPC H03B27/00 

FIELD: electronics.

SUBSTANCE: invention relates to electronics and can be used in measurement techniques and automation. Function generator includes three multipliers (1-3), two integrators (4, 5), three squaring devices (6-8), two adders (9, 10) and a relay element 11, third 12 and fourth 13 adders, second relay element 14, fourth squaring device 15 and fourth multiplier 16.

EFFECT: technical result is broader functional capabilities of device by producing at its outputs quadrature harmonic signals and quadrature signals of bipolar rectangular and triangular shapes with high metrological characteristics when frequency is varied over a wide range.
