Signal Transmission - Assignment ExampleThe length of the antenna should be more or equal to the wavelength. In order to transmit high wavelength frequency, the length of the antenna should be larger that set about unpractical. In order to limit the size of the antenna, carrier frequencies are use that have powerful argue frequencies. immune carrier frequencies make it possible to send and receive the radio waves under a set direct range. It limits the distortion and interference with other frequencies. Carrier frequencies allow the transmission of the signal frequencies to be transmitted wirelessly. radio set waves require carrier frequencies for the transmission as carrier frequencies make it easier to transmit the information through space. Carrier frequencies work in a fixed band where the power transmitted through the carries is considerably higher as compared to that of the packed radio frequencies. Carrier frequencies are transmitted by using a connatural physical trans mission medium. Signal frequencies and carrier frequencies are modulated in a manner that the telephone receiver can easily separate the two frequencies. Mainly two basic transition techniques are used for the transmission of the carrier frequencies. Frequencies modulation and amplitude modulation are the basic types of modulation techniques used extensively. In frequency modulation, the signal frequencies are mixed with the frequency of the carrier frequency and in amplitude modulation techniques, the signal frequencies are mixed with respect to the amplitude of the carrier frequency.
