                              HOW TO CALCULATE SNR?









              QUESTION 1





                An amplifier has an Input Signal Power (Sin) of 100W and Input Noise

                Power (Nin) of 0.001W, as well as Output Signal Power (Sout) of 100W
                and output Noise Power (Nout) of 0.04W. Calculate the value of Signal
                to Noise Ratio (SNR) for an input and output.

                [Answer :  SNR = 50 dB]
