D)Receiver

A device that converts one from of energy into another form is termed as

A simple machine can convert one form of energy to the other.

Write the functions of the following in communication systems: (i). Receiver (ii). Demodulator

Write the functions of the following in communication systems: (i). Receiver (ii). Demodulator

One form of energy cannot be converted into another form. True/False.

Is it practically possible to convert a form of energy completely into another useful form ? Explain your answer

Draw a block diagram of a generalized communication system. Write the functions of each of the following: (a) Transmitter (b) Channel (c) Receiver .

There is always some loss of energy in conversion from one form of energy to another form, so the total energy is not conserved. True/False.

Dimensional formulae are used A) to convert one system of units into another (B) to find proportionality constants C) to cheak the correctness of an equation

(a) Why is electric energy considered most desirable forms of energy ? (b) Name two devices which convert electric energy into : (i) heat energy only (ii) heat and light energy. (iii) mechanical energy (iv) magnetic energy.
