Abstract
1389813 Measuring parameters of oscillatory circuits PENZENSKY POLITEKHNICHESKY INSTITUT 6 June 1973 27066/73 Heading G1U An arrangement for measuring two parameters of an oscillatory circuit comprises a voltage step generator, a reference impedance, an amplifier, an amplitude measuring circuit and a frequency measuring circuit. In use, for testing series oscillatory circuits 2,3, Fig.1, the oscillatory circuit forms the input circuit to the amplifier 4, and the reference impedance 5 forms a feedback loop for the amplifier, and for testing parallel oscillatory circuits 11, 12, Fig.4, the reference impedance 10 forms the input circuit to the amplifier 4 and the oscillatory circuit the feedback loop. To effect the test in Fig.1, a voltage step of magnitude E is applied to the oscillatory circuit 2, 3, and the resulting oscillatory signal produced by the amplifier has its amplitude A measured by a circuit 6 and its frequency f measured by a circuit 7. It can then be shown, in an obvious notation, that- The arrangement shown in Fig.4 operates in a similar manner. The reference impedance may be a capacitor Figs. 2 and 5 (not shown) or an inductor Figs. 3 and 6 (not shown).
