The equivalent noise resistance for an amplifier is300Ω, and the equivalent shot noise current is5μA. The amplifier is fed form a150Ω, 10μArms sinusoidal signal source. Calculate the individual noise voltages at the input and the input signal to noise ratio in decibels. The noise bandwidth is10MHz.
