Q21 of 30 Page 103

Figure 15.3 shows a communication system. What is the output power when input signal is of 1.01mW? (gain in dB = 10 log10 (Po/Pi).


Given,

Input power,


Loss suffered in transmission


Gain due to amplifiers =


Total gain =


Let the output power be .






Hence, the output power is .
