उत्तर
A basic communication system consists of BADEC.
Explanation:
A basic communication system consists of an information source, a transmitter, a link (channel) and a receiver or a communication system is a set-up used in the transmission and reception of information from one place to another.
The whole system consists of several elements in a sequence. It can be represented in the diagram given below:

A 1 KW signal is transmitted using a communication channel which provides attenuation at the rate of – 2dB 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")]`
Audio sine waves of 3 kHz frequency are used to amplitude modulate a carrier signal of 1.5 MHz. Which of the following statements are true?
