              QUESTION 5





                An  amplifier  has  the  output  signal  voltage  8V  and  output  of  noise

                voltage 0.006V. If the input resistance is 50Ω and the output resistance
                is 75 Ω, what is the signal to noise power ratio of an amplifier.
                [Answer :   64.27 dB]
