              QUESTION 6





                Given the Noise Figure (NF) of a non amplifier is 7dB. At the output, the

                signal  power  is  300  µW  and  the  noise  is  2  µW.  Calculate  the  Noise
                Factor (F) and the input signal to noise power ratio (SNRin)
                [Answer :  SNR  150 dB,  SNR in : 751.8, Noise Figure : 5.012 ]
