Abstract
A shift register generator feedback tap identification system in which a received code is fed to a register which detects when the code contains all 1's at which time a bit position counter and a variable tap shift register generator are reset and a null-filter is enabled. The bit position counter controls the tap positions of the variable tap shift register generator and the output thereof is fed to the null-filter which compares the received code with the code from the variable tap shift register generator.
