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 statistical estimation of nonlinear distortions has two division units, two statistical units and subtraction unit. Output of subtraction unit has to be information output of device. Input of first statistical unit has to be first test input of subtraction unit. First output of first statistical unit is connected to first input if first division unit. Output of first division unit is connected with first input of subtraction unit of device. Second input of subtraction unit is connected to output of second division unit. First input of second division unit is connected with first output of second statistical unit. Input of second statistical unit has to be second test input of device. Second input of first statistical unit is connected with second input of second division unit. Second output of second statistical unit is connected with second input of first division unit. Amplification factor of tested four-terminal network is estimated additionally.
EFFECT: widened functional abilities.
