Signal discrimination unit

Abstract

Abstract PURPOSE: To eliminate distortion of transmission lines having linear and non-linear transmission characteristics and prevent erroneous decision form being propagated, by providing a temporary decision means and a pattern estimation means. CONSTITUTION: The signal inputted from input terminal 100 is sampled by sampler 1 and is decided as 0 or 1 by comparator 2 forming a temporary decision means. Data decided temporarily is inputted to shift register-type memory circuit 4 which is a pattern estimation means. Then, the sampled analogue voltage is not only inputted to reliability decision means 7 but also inputted to final decision circuit 6 through delay line 3. Correction quantity memory circuit 5 stores a distortion correction quantity determined previously correspondingly to the signal pattern to be estimated by pattern estimation means 4.
