ABSTRACT:
A circuit arrangement for amplifying a periodic signal and for adjusting a reference level contained therein, in which a charging/discharging arrangement alternately supplies charging or discharging currents to a storage means, depending on whether the value of a periodic signal exceeds or is exceeded by a limit value, such that a mean value at least substantially corresponding to the reference level occurs at the storage means includes a compensator means which adjusts the charging and disharging currents by a compensation factor which is selected such that the ratio of the charging current to the discharging current is independent of fluctuations in current resulting from variations affecting the gain factors of amplifier components comprised in the amplifier means.
