Abstract
A receiver for receiving digital data after transmission through a channel which produces inter-symbol interference or other distortion. In one embodiment, a received signal is differentiated before being digitized to form an output digital bit stream, to reduce the effects of inter-symbol interference and other distortion in the channel. The differentiated signal is compared to two threshold values, a first threshold value, and a second threshold value, the first threshold value being greater than the second threshold value. When the differentiated signal exceeds the first threshold, the output bit is 1, when the differentiated signal is less than the second threshold value, the output bit is 0, and when the differentiated signal is between the first threshold value and the second threshold value, the output bit is the same as the previous output bit.
