Abstract

Abstract In this paper of the series on multi-resolution Fourier analysis, labeled NY-MFA, it is shown that the problem of finite observation and its detrimental consequences on amplitude resolution are eliminated. Obscuring and distorting effects of implicit windowing are suppressed without altering already provided frequency resolution in excess of Gabor–Heisenberg limit. Weak, virtual or spurious spectral lines are detected. Easier and fine frequency estimations are provided. Proposed analysis opens promising perspectives free of finite observation effects helping, by the way, to avoid misleading interpretations and diagnosis errors.
