Abstract: The invention relates to a digital low frequency correction circuit and a corresponding method for correction of low frequency disturbances within a digital signal, in particular to a reduction of distortions caused by analog circuitry, such as analog signal amplifiers. The low frequency correction circuit comprises a main signal path adapted to delay a digital input signal received by a signal input terminal and at least one correction signal path including a digital correction filter adapted to filter the received digital input signal. Furthermore, an adder of the circuit is adapted to add the digital signal delayed by the main signal path and the digital signal corrected by said correction signal path to generate a digital output signal output by a signal output terminal of the circuit.
