Abstract
A signal quality measuring apparatus includes a binary signal generating unit to generate a binary signal from an input signal; a level information extracting unit to extract level information from a relationship between the input signal and the binary signal using at least two window lengths; and a quality calculating unit to calculate a quality of the input signal based on the level information.
Claims22
A signal quality measuring apparatus comprising:
- a binary signal generating unit configured to generate a binary signal from an input signal;
- a level information extracting unit configured to extract level information from a relationship between the input signal and the binary signal using at least two window lengths;
- and
- a quality calculating unit configured to calculate a quality of the input signal based on the level information,
- wherein the at least two window lengths are determined according to a maximum run-length and a minimum run-length of the input signal,
- wherein the level information extracting unit comprises sub-level information extracting units corresponding to the at least two window lengths.
