Abstract

Described is an electrical measuring system with a six-gate circuit and a delay line. An electrical signal is fed from a resonator, at least one of directly and or via the delay line, to the six-gate circuit. The frequency of the signal is computed by the six-gate circuit in dependence on the length of the delay line.
