A signal processing device which selects a signal, using for example, a channel selector in a television receiver or a source selection circuit in an amplifier, and compensates automatically for differences in signal parameters, such as volume of sound or picture brightness, between the signal sources. Corrections which are applied to the relevant parameter within a given time interval after source selection are divided within the time interval between a global value and a local value (for example an offset) for the relevant signal source. |
