A ` 1 KW ` signal is transmitted using a communication channel which provides attenuatiom at the rate of ` - 2 dB per km` . If the communication channel has a total length of ` 5 km` , the power of the signal received is [ gain in `dB = 10 log ((P_(0))/(P_(i)))]`A. 900WB. 100WC. 990WD. 1010W
Assertion: Amplification is necessary to compensate for the attenualtion of the signal in communication system. Reason: Amplification is the process of increasing the amplitdue and consequently the strength of a signal using an electronic circuit.
