SIGNAL QUALITY MEASURING APPARATUS AND METHOD THEREOF

摘要

PURPOSE: A signal quality measuring apparatus and a method thereof is provided to measure the quality of an input signal by using the level information of an extracted input signal from the relation between an input signal and the binary signal of the input signal. CONSTITUTION: A binary signal generating unit(110) generates a binary signal from an input signal. A level information extraction unit(120) extracts the relation between input signal and the binary signal by using the length of at least two windows. A quality operation unit(130) computes the quality of an input signal by using the extracted level information.
