Abstract
A device processes signals from a plurality of signal channels that are received in parallel. A channel processing circuit (), applies a series of filtering operations selectively to the signal from a first one of the signal channels. A filter management circuit () detects a reception condition from reception of a signal in a second one of the signal channels. The filter management circuit () controls application of at least a part of said filtering operations to the signal from the first one the signal channels by the channel processing circuit (), dependent on the detected reception condition. Selected filter operations may be enabled or disabled. Thus, power consumption may be reduced. In an embodiment, the detected reception condition is determined as a by-product of functional reception of another channel. Thus power consumption for the detection of the reception condition is also reduced. From reception of specific types of channels, for example, it may be detected whether the device is indoors or outdoors and filtering of other channels may be adapted accordingly.
