Abstract (en)

[origin: WO2004105382A1] A signal processing circuit (1) comprises a first signal generator (10) which generates a DC-level (DL). A second signal generator (11) generates an AC-signal (AS) which is not related to the DC-level (DL). A combining circuit (12) combines the DC-level (DL) and the AC-signal (AS) into a combined signal (CS). And a common processing circuit (13) processes the combined signal (CS).
