  • Abstract
    The standard measure of television-tuner input-tube performance has become the noise figure. From this first amplifier tube in the receiver nearly all of the snow and hiss in the picture and sound originate. A tube or circuit that can reduce this snow and hiss is greatly to be desired. The noise figure is a measure of an amplifier´s tendency to generate the noise that results in this snow and hiss.
