FIELD: electro-radio measurements.
SUBSTANCE: device allows estimating availability and degree of nonlinear distortions in four-terminal networks when random signal pass through them. Device for statistic estimation of nonlinear distortions has two division units and two statistical units. Input of first statistical unit has to be first test input of device. First output of statistical unit is connected to first input of first division unit. First output of second statistical unit is connected to first input if second division unit. Input of second statistical unit has to be second input of device. Third division unit is introduced into device which division unit has output to be output of device. Second output of first statistical unit is connected to second input of second division unit. Second output of second statistical unit is connected to second input of first division unit. Outputs of first and second division units are connected to first and second inputs of third division unit correspondingly. Amplification factor of tested four-terminal network is estimated additionally.
EFFECT: widened functional abilities.
