Term Paper on Application of Analog Modulation Techniques

of Analog Modulation Techniques Term Paper:

Modulation in physics is the time alteration of the chosen properties of the regular physical processes. The practical application of modulation is the overlay of the low-frequency information signal on high-frequency signal carrier for the long-distance transmission. In order to transmit signal on long distances, they require much energy.

It is obvious that the signals with higher frequency possess more energy. On practice the signals which carry the certain information (for example, speech) have low-frequency vibrations, so in order to transmit them on the longer distances one requires to increase the frequency with the help of overlaying the informational signals of the lower frequency on the signals of the higher one. There are several types of modulation in electronics – analog, digital, pulse and miscellaneous modulation techniques.
