About: Effective input noise temperature

An Entity of Type: species, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In telecommunications, effective input noise temperature is the source noise temperature in a two-port network or amplifier that will result in the same output noise power, when connected to a noise-free network or amplifier, as that of the actual network or amplifier connected to a noise-free source. If F is the noise factor numeric and 290 K the standard noise temperature, then the effective noise temperature is given by T n = 290(F − 1).

  • In telecommunications, effective input noise temperature is the source noise temperature in a two-port network or amplifier that will result in the same output noise power, when connected to a noise-free network or amplifier, as that of the actual network or amplifier connected to a noise-free source. If F is the noise factor numeric and 290 K the standard noise temperature, then the effective noise temperature is given by T n = 290(F − 1). (en)
  • 電気通信において、実効入力雑音温度は二端子対回路もしくは増幅器のソース雑音温度で、実際にはノイズのないソースに接続された回路網もしくは増幅器である、ノイズのない回路網もしくは増幅器に接続していると、出力雑音パワーと同じになる。雑音指数を Fとしたとき、標準雑音温度が290 K である場合、実効雑音温度 Tn は 290(F-1) となる。 (ja)
