Match List I with List II.
$$\begin{array}{|l|l|l|l|}\hline & \text{List I} & & \text{List II} \\ \hline \text{A.} & \text{Attenuation} & \text{I.} & \text{Combination of a receiver and transmitter} \\ \hline \text{B.} & \text{Transducer} & \text{II.} & \text{Process of retrieval of information from the carrier wave at receiver} \\ \hline \text{C.} & \text{Demodulation} & \text{III.} & \text{Converts one form of energy into another} \\ \hline \text{D.} & \text{Repeater} & \text{IV.} & \text{Loss of strength of a signal while propagating through a medium} \\ \hline \end{array}$$
Choose the correct answer from the options given below:
Answer: (D) A-IV, B-III, C-II, D-I
- Attenuation: loss of signal strength in the medium → IV
- Transducer: converts one form of energy to another → III
- Demodulation: recovering the message from the carrier → II
- Repeater: a receiver and transmitter combined → I
