Method of and apparatus for shaping waveform and method of and apparatus for generating threshold for waveform shaping

摘要

A waveform shaping method including a step of detecting at least two items selected from three items i.e. a signal time width, a peak value level, and a signal failure time width of an input signal in a unit time length, a step of converting for each of the detected items a detected value into a function value based on a function representing likelihood of a logical value "1" or "0", a step of conducting a predetermined computation on the converted function values related to the at least two items to attain a result, and a step of discriminating the result of the computation by a predetermined threshold value to determine a logical value "1" or "0" for the input signal in the unit time length.
