Discrete-Level Broadband Excitation Signals: Binary/Ternary Chirps

This research deals with using of discrete-level chirp signals as the excitation ones for bioimpedance measurement. Discrete-level (binary, ternary) chirps simplify the necessary hardware and software in the development of respective devices essentially, but assure the wide frequency range measurements and high energy-efficiency at the same time. Mostly the chirps with instantaneous frequency, which is changing by a power function, is treated. Ill. 6, bibl. 7, tabl. 2 (in English; abstracts in English and Lithuanian).
