In this article some results of comparative analysis of mostly used terrestrial radio signal sources are published. The aim of this observation is to utilize the sources signal as a common signal source in building Time and Frequency Synchronization System, according to common views algorithm. As a common sources digital TV broadcasting of (DVB-T2) signals and analog (Secam) TV signals were investigated. The correlation properties of this signals are investigated theoretically and practically. The list of equipment used in investigations: TV and FM signal receiver, digital oscilloscope, and software for calculation of inter- and autocorrelation functions and statistics. The correlational and statistical analysis proved that the signals of digital television format DVB-T2 can be effectively used as a general source for synchronization time and frequency scales by using common views algorithm.
