The object of study is one- and two-stage signals of the carrier and with amplitude modulation RNS LORAN-C. The purpose of the work is to study the degree of influence of various temporal parameters of transistors on the levels of side harmonic components at the operating frequency of the RNS LORAN-C. Single- and two-stage carrier signals and amplitude-modulated signals were investigated. A theoretical analysis of the influence of the accuracy of the formation of control signals on the spectral characteristics was carried out. |
