An optical communication system. Having an operating wavelength `lambda` (in metres), can use only `x%` of its source frequency as its channel bandwidth. The system is to be used for trasnmitting TV signals requiring a bandwidth of F hertz. How many channels can this system transmit simultanously?

Text Solution

Optical source frequency , `v=(c)/(lambda)`Hz, Band width of channel =x% of v,=`(x)/(100)v=(x)/(100)(c)/(lambda)`, `Number of channels =("total bandwidth of channels")/("bandwidth for one channel")`=`(xc)/(100lambdaF)`

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 frequency range allotted to FM radio broadcast is 88 MHz to 108 MHz. Which of the following communication channels can be used for its transmission? A. Sky wave communication only B. Space wave communication only C. Satellite communication only D. Either space wave communication or satellite communication

Communication system is some set up used to convey some type of information in the form of voice, data or picture from one point to other in its true or original form. During transmission of information some phenomenon change the originality of information. Can you match these processes affecting the originality of information mentioned in Column-I with their meaning to be understood by you in Column-II ?
