Abstract: | Conclusions Two-way electronic measuring instruments can have circuits with simultaneous, consecutive, or periodic conversion. (Comparator instruments with alternating periodic conversion of the compared voltages or currents are known as periodic comparator instruments 11]).The electronic measuring instruments with periodic conversion have several advantages characteristic for instruments with consecutive conversion (they have constant measured information in the conversion channel, a wide frequency range, and they do not require selection of elements with identical parameters). Since the output signal of the electronic measuring instruments with periodic conversion is proportional to the measured quantity, these instruments can be provided with a closed structural circuit, thus raising their measurement precision.Translated from Izmeritel'naya Tekhnika, No. 4, pp. 42–46, April, 1969. |
