<p>A receiver having a variable bit slicer for detecting bits in a demodulated signal, comprises a demodulator (14) for deriving a demodulated bit rate signal, means (36) for storing a plurality of threshold values, each of the threshold values being selectively adjustable, means (28, 38) for selecting the threshold value for comparison with the current bit signal (Sn) in response to a sequence of N bits (where N is at least 2) (Bn-1 , Bn-2) received prior to the current bit (Bn) and means (38, 40) for using the current bit to update the selected threshold value. Also disclosed is a method of dc offset correction (Figure 7).</p> |
