    Knowing the Output signal to noise ratio and the input signal to noise ratio of an amplifier.

    I have to find the noise factor.

    The output signal to noise ratio is 63.01dB and the input signal to noise ratio is 40dB.

    Is it just F= I/P signal to noise ratio / O/p signal to noise ratio?

    giving me F = 0.63dB

    or isit F=10log10 I/P signal to noise ratio / O/P signal to noise ratio?

    giving me F = 1.97dB

    Hope someone can help
    Cheers
