WebThirdly, a resistor attenuator will introduce noise but it may easily be small compared to the noise that is being attenuated. Fourthly, if the noise into an attenuator is X, that noise will be reduced by the same factor as any signal would be. If the attenuator is 2:1 then the output noise will be X/2.
