The present invention has been made in an effort to provide a system and an analysis method that judges a brain state of a user by analyzing a brain wave of the relevant user without a highly skilled expert's help to provide the judgment result to a brain wave training program for being skilled in a brain operating system (BOS). A brain wave analysis system according to the present invention includes: a data input unit that receives and stores brain wave data inputted through at least one electrode attached to a scalp of a human body and predetermined response data; a data sampling unit that converts the brain wave data and the response data into sampling datasets; a dataset combining unit that converts the plurality of sampling datasets into one combination dataset; a time section selection unit that selects a first time section serving as an analysis target with respect to the combination dataset; a noise reduction unit that generates a final dataset from which unnecessary signal components are removed from the combination dataset in which the time section serving as the analysis target is selected; and a data analyzing unit that judges the state of the brain wave of the human body by applying a brain wave analysis algorithm to the final dataset.
