Abstract
A method for determining an offset of a periodic signal is provided, wherein an offset value caused by a level change of the periodic signal is suppressed. The periodic signal is fed to first and second integrators and to a periodicity recognition unit, wherein the first integrator is integrated over a full period. The second integrator is integrated over a full period offset by a half period. Starting times of integrations are controlled by the periodicity recognition unit. Output signals of the integrators are stored in two memories, wherein the output signals are summed and a sum signal represents the offset of the periodic signal. The output signals are fed to a comparator circuit. The sum signal is stored in a further memory as an output signal, wherein the comparator circuit triggers the further memory to continue outputting a value of the output signal stored in the further memory.
