摘要： Ratio measuring apparatus adapted to measure various parameters of impedance elements is comprised by a multiplier energized by a divisor signal, and an integrator supplied with a dividend signal and the output from the multiplier. A portion of the output from the integrator is fed back to the multiplier so that the integrator provides an output proportional to the ratio between the dividend signal and the divisor signal.
