FIELD: testing equipment being used in mechanical engineering. SUBSTANCE: device to determine parameters of linear mechanical oscillating system has the forth multiplier, the first and the second amplifiers, a block to divide by two, the third transformer. The first transformer output and output of power source of π voltage are connected to inputs of the forth multiplier the output of which is connected through the first amplifier to the third output of the device, and through the second amplifier to the forth output of the device. The first transformer output is connected directly to the fifth output of the device. The first transformer input is connected to the sixth output of the device through the third transformer, output of which is connected to the seventh output of the device through the block to divide by two. EFFECT: increase in information content. 1 dwg
