Each letter in the word is represented by different signal amplitude using thirty two scale order. If we do so information flow speed gets greatly increased as per Hartley law. Since now each letter is represented by one symbol instead of five. But in such a case noise will cause numerous error making the system useless extremely large transmitting power is used.

A general communication system consists of information source, transmitter, channel, receiver and destination. Information or intelligence is basically a physical quantity such as mass or length. Thus when we speak of one kilo gram of a given object it is immaterial what the material is concerned whether it is gold or brass or silicon. Information theory is a scientific study of information and the communication systems design to handle it.

The functions performed by repeaters are amplification and frequency down conversion. Repeater amplifies signal from a low power level of the order of negative hundred decibels watt to an output power level of the order of ten decibel watts thus providing again of the order of hundred and ten decibel.

Apart from noise, other forms of interference are found in radio receivers such as image frequency, transmitters operating on an adjacent channel and transmitters operating on the same channel. Frequency modulation provides not only improvement in the sound noise ratio but also greater discrimination against all other interfering signals, no matter what their source.

The principal advantage of Pulse Code Modulation (PCM) is the noise immunity. But it is not used exclusively. Other pulse modulation systems are still used in spite of highly superior performance of PCM.
