Erratum to “Octonion Fourier Transform of real-valued functions of three variables - selected properties and examples” [Signal Process. 136 (2017) 29-37](S0165168416303358)(10.1016/j.sigpro.2016.11.021)

摘要

An error has been discovered in Section 6.2 of the article mentioned in title of this paper (one statement is true in some special cases but not in general). Fortunately, this error affects onlySection 6.2 and 6.3 (which are last two short sections of this article, excluding conclusions and final remarks) and has no effect on previous sections. We were able to find a correct solution and can provide a detailed discussion considering the notion of the autocorrelation function and the energy spectral density (which was misstated in the article as the power spectral density)
