AM 방식의 수중통신
An underwater communication by AM technic
초록
An underwater communication technic using AM modulated ultrasonicwave was studied. The experiment were performed in the ahechoic water tank with 60KHz carrier wave and the frequency response of the system by demodulated signals were measured varing the degree of modulation and distance between transmitter and receiver. The bandwidth of transmitted signals was limited by the acoustic characteristics. As the result, it was found out that this kind of system is applicable to the underwater speech communication.
