Assertion : Communication in UHF/ VHF regions can be established by space wave or tropospheric wave. Reason : Communication is UHF/VHF regions in not limited to line of sight distance but can be achieved for very large distances

Statement-1: Communication in UHF/VHF regions can be established by space wave or tropospheric wave. Statement-2 : The refractive index of the ionosphere becomes very high for frequencies higher than the critical frequency.

Assertion: Lond distance communication between two points on the earth is achieved using sky waves. Reason: sky wave propagation takes place above. The frequency of 30 MHz.

What is the line of sight communication? (ii) Why is it not possible to use sky waves for transmission of T.V. signals? Upto what distance can a signal be transmitted using an antenna of height h?

Assertion: The potential difference between the two conductors of a capacitor is small. Reason : A capacitor is so configured that it cofines the electric field lines within a small region of space.

Perhaps, the most commonly used mode of communication involves use of free space as a communication channel between transmitter and receiver. The various possible modes of using of free space have been described below Ground wave communication : This mode is used for low frequency as at high frequency, losses become large. This is useful for distance of the order of 1 km. Space wave communication: The signals are transmitted directly from transmitter to receiver. There is no limit to upper frequency, but its range is limited to few hundred kilometers. The range depends on the height of transmitting antenna Sky wave communication : The signals are sent towards sky They are reflected back towards earth by ionosphere. Its range can be above 500 km. But, very high frequencies (above 10 MHz) are not reflected back. Satellite communication: The signals that cannot be reflected back by ionosphere are reflected back by satellite. Moon is a passive satellite of earth. The cordless phone installed in a house uses

is the set up used in the transimiision of information from one place to another. The present day communication systems are electrical, electronic or optical in nature. Three parts of a communication system are: Transmitter: Communication Channer and Receiver. A signal is defined as a single valued function of time. This function has a unique value at every instant of time. Most of the speech or information signals cannot be transmitted directly over long distances. They have to be modulated suitably and then trasmitted. Communication channer carries the modulated wave from transmitter to receiver. The air, transmission lines and free space are the common communication channels. the reciever consisits of a pickup antenna, a with the help of the above passage, choose the most appropriate alternative to each of the following questions: Communication systems may be
