PPT-System noise temperature and G/T ratio

By SSadhish Prabhu Noise temperature It provides a way for determining how much thermal noise is generated by active and passive devices in the receiving system At same physical temperature at the input of the amplifier .

When the CT’s are mounted on the transformer primary windings, the user needs to install jumpers on the secondary windings to eliminate the Turns-Ratio reading errors.

The attenuation produced, in dB per meter run of duct, depends ‎on α, the sound absorption coefficient of the lining material and the ratio of perimeter to cross ‎sectional area of the duct (P/S).‎. produced by different activities.
