摘要
Each voltage to be measured is passed through its own amplification channel, and its magnitude and phase are are evaluated in a common measurement device. At first all amplification channels are adjusted so that they deliver output voltages with the same amplitudes and phases. - An auxiliary voltage of the same frequency is then applied to the channels which all retain their previous adjustment. Amplitudes and phases of original signals are derived from new signals delivered by the amplification channels. The energisation of the direction finder is provided by two oscillators (7,10) leading to the amplifier (12).
