FIELD: measuring technology. SUBSTANCE: circuit has mutual-inductance transformer 3, integrating unit 2, and pseudorandom unit 1 which adds a meander oscillation to the signal from transformer 3 ahead of unit 2 in order for unit 2 to provide a signal representative of measured current perturbed by a triangular pseudorandom signal. EFFECT: improved design. 1 dwg |
