Report is concerned with heuristic development of basic features of pulse-frequency modulation, used in number of spacecraft; advantages are its noise-immunity characteristics and ease of generation; present method of formating and synchronization is presented to illustrate convenient handling of analog and digital data; theory of group-coded binary sequences is derived by using special type of correlation matrix; analysis of excitation of unmatched filter to step sinusoid is carried out to indicate magnitude of errors affecting direct frequency measurement of pulsed sine wave; experimental results from spectral analyses of satellite recordings.
