Abstract
A bit detecting process for identifying binary bit values of digitized signals whose bit amplitudes may be distorted. A digital signal which represents the amplitude of a bit at discrete clock intervals is generated and the difference between a threshold value and the value of the digital signal is determined. A first integral method algorithm or a second second-order difference method algorithm, each of which identifies the binary value of the bit, is selected as a function of the determined difference.
