Abstract:
A communication signal receiver for enabling switching from an active mode to a passive mode in order to reduce power consumption, the receiver comprising:a plurality of components arranged along at least one signal path, the components along the signal path comprising a filter for processing a received signal and averaging means for deriving a mean value of the signal, wherein an output of the averaging means is connected to a selector located prior to the filter along the signal path, and control means in communication with the selector, the control means for detecting an event in the signal indicative of a last data symbol and responsive thereto controlling the selector so as to cause the selector to supply the mean value comprising a DC level to the filter in response to detection of the event in the signal so as to enable components arranged prior to the selector along with signal path to be switched from the active mode to the passive mode.
