Abstract

A voltage-frequency converter having a chargeable and dischargeable memory, a comparator circuit and a subsequent multivibrator, wherein the charging and/or discharging signal for the memory is obtained from special signal sources. At constant charging and discharging signals, a linear voltage-frequency conversion is provided. In the case of variable charging or discharging voltages, non-linear signal conversions are possible. The multivibrator may be a digital monostable multivibrator, to effect precise, reproducible and quantifiable period durations in the output signal of the converter, and thus a very precise voltage-frequency conversion.
