Telecommunication - Essay Example Today communication is carried out over long distances using pictures and audio, which compromises of music and voice. The sound at present, transfers throughout the world through electricity. Electricity is, therefore, an important part of communication. Radios and television produce the output of various visual and audio signals. They act as the final point where the data that has been transferred from the stations offering audio and video. The audio and video are transmitted through equipment that helps in converting to electrical signals, which are then transferred over long distances (Noll, 1995). Signals are an important part of communication. They are classified according to the frequencies they have. The various signals are used in radios and television where audio and video are transmitted over different frequencies. UHF and VHF are the frequency bands related to television. The transmitter sends the audio and video through the communication channel. Signal carry visual and audio through transmission channels to the point of final output. The radios and television receiver the signals from the receiver and a person can tune to get the audio or videos. Spectra helps to differentiate between the various waves and the frequencies of the waves. Different electromagnetic waves characterize the signals transmitted over a communication channel. They are used in delineating the various media and communication channels and signals. Bandwidth is usually allocated to communication channels depending on the different frequencies in the signal. Electricity plays an important part in communication since in the modern world signals transmitted with the help of electricity. Power circuits are affected by inductance and capacities, which helps in filtering the various signals. Inductance and capacitance play a greater role in differentiating the signals into the different frequencies and thereby enabling the transmitted message to reach the intended point. The
