In this work, the spectra of the direct binary modulation and the orthogonal multi-frequency modulation are calculated. It is shown that binary sequence transmission by the method of multi-frequency modulation reduces the out-of-band radiation. Thus, decreases the inter-symbol interference as well as the transition noise in multi-channel systems.
