As in radio communication, individually television station is allotted different carrier frequencies to mis follow selection of want station at the receiving end. The TV sort out receiver has tuned circuits in its input section called tuner. It selects desired channel signal out of the many picked up by the antenna.

Thus, at any instant at that place are almost an immortal number of pieces of information that desire to be picked up cooccurringly for transmitting picture details.
