NAVAL AIR DEVELOPMENT CENTER JOHNSVILLE PA ANTI-SUBMARINE WARFARE LAB
Pagination or Media Count:
This investigation is concerned with intensity modulation theory of frequency intensity modula tion design of a frequency intensity modulation system and comparison of frequency intensity modulation FIM and amplitude insnnsity modula tion AIM systems. Although most of the dis cussion is confined to cathode-ray tube display systems, the techniques are applicable to non linear display devices and non-linear transducers. Author
