The accurate estimation method of the basic frequency and hamonics of sinusoidal signals distorted by hormoics

고조파에 의해서 왜곡된 정현파의 정확한 주파수 추정 방법

This paper proposed frequency estimation the method of distorted sinusoidal signals by harmoics. An approximate estimation based on FFT and the accurate basic frequency was estimated by proposed method with Fourer Series, and the harmonics were estimated by the basic frequency. The sinusoidal signals is extracted by filter banks based on the estimated hamonics. The rate of basic and hamonics power is estimated by the extracted sinusoidal signals and we developed their algorithm and programs.
