From a source with Pin = 2.4 mW, we want to get Pout = 60 mW at a distance l = 20 km from the source. α for the transmission line is given to be 2.3 dB/km. The available amplifiers have adjustable power gain, but are subject to two limitations: (i) the input signal power must be at least 1 µW to overcome internal noise, and (ii) the output signal power must not be greater than 1 W to avoid nonlinear distortion. Design an appropriate system.
Three sine waves along with frequencies 100Hz, 200Hz and 350Hz and with amplitudes of 1V, 2V and 1.5V correspondingly, are added together to make a single waveform. What is the min
