Przedstawiono opis oraz zastosowania zupełnie nowego rodzaju sygnału - wieloczęstotliwościowego sygnału koherentnego. Sygnał ten jest zbiorem wielu niezależnych względem siebie sygnałów analogowych, synchronicznych względem jednego, wspólnego sygnału zegarowego. Okres każdego z tych sygnałów jest całkowitą wielokrotnością okresu sygnału zegarowego. Wieloczęstotliwościowy sygnał koherentny umożliwia...
In this paper a method allowing simultaneous measurement of tested objects using many periodic signals and applied to a receiver of the authors' design has been described. Frequencies of the signals were chosen in such a way that the measurement executed is the coherent measurement of all used signals. The receiver was applied effectively to measurements of HF signals utilizing an 1&Q demodulator...
