tromagnética can carry information in words, sounds and images, is the need to modulate it. Modulation is a process by which modifies some characteristics of this wave, transforming send her into a signal. But what is the relationship between the signs UHF with the solution of the problem? This is especially relevant for the solution of our problem, because the distance from the boat to plane, considered in terms of transmission of radio signal, is relatively small. The signal emitted and received by radios in question "presents an almost linear behavior." Another point worth noting is that the signal transmission in which we are treating "provides a better performance in the presence of noise and interfering signals" We emphasize that the radio transmitters and receivers have UHF signals in its operating mechanisms, balanced by a discriminator which you can adjust the transmitting and receiving mode that provide excellent linearity in the signal path. This means that when the radio the plane first capture the signal from the boat and the aircraft to continue flying in the same direction at any given time, you lose the signal. The first capture the signal , for us, is a point. The moment you lose the signal , we have another point. We can say that the capture signal is the point of the boat that we call the center of a circle, and you lose the signal , the other point, that here we say belonging to the circle. ACTIVITY Now it's up to you!! Use approach concepts in Figures 1 and 2, and continue to build a response to the problem. SEARCH Of course, the study of acoustics, whose signals UHF and VHF are objects of study, does not end here, and are not very common in our daily life, even every day we watch television and listen to radio. Therefore, it is justified to search for other answers and seek relationships with our problem.

tromagnética može nositi podatke riječima, zvukove i slike, je potreba da ga modulira. Modulacija je proces kojim se modificira neke karakteristike ovog vala, pretvarajući ju poslati u signalu. No, ono što je odnos između znakova UHF s rješenjem problema? To je posebno važno za rješavanje našeg problema, jer je udaljenost od broda do zrakoplovom, smatraju u smislu prijenosa radio signala, relativno je malen. Signal emitira i prima radio u pitanje "predstavlja gotovo linearno ponašanje." Druga točka napomenuti je da prijenos signala u kojem smo se liječenje "pruža bolje performanse u prisutnosti buke i ometaju signale" Naglašavamo da je radio odašiljača i prijemnika imaju UHF signale u svojim operativnim mehanizmima, uravnotežena od diskriminator koji možete prilagoditi prijenosnu i dostave način koji pružaju izvrsnu linearnost u putu signala. To znači da kada je radio zrakoplov prvi uhvatiti signal sa broda i zrakoplova za nastavak leti u istom smjeru, u svakom trenutku, što izgubiti signal. Prvi hvatanje signala , za nas, je točka. U trenutku kada gubi signal , imamo još jedan bod. Možemo reći da je hvatanje signala je točka na brod koji zovemo središte kruga, a što gube signal , druga točka, da ovdje kažemo pripada u krug. AKTIVNOST Sada je na vama! Koristite prilaz pojmove na slikama 1 i 2, i dalje graditi odgovor na problem. TRAŽI Dakako, studij akustike, čije signale UHF i VHF predmet su istraživanja, ne završava ovdje, a nisu baš uobičajena u našem svakodnevnom životu, čak i svaki dan gledamo televiziju i slušati radio. Stoga, opravdano je tražiti druge odgovore i traže odnose s našim problemom.
