Input Arguments
|
Noise figure in decibels. The noise figure is the ratio of the actual output noise power in a receiver to the noise power output of an ideal receiver. |
|
Reference temperature in kelvin, specified as a nonnegative scalar. The output of an ideal receiver has a white noise power spectral density that is approximately the Boltzmann constant times the reference temperature in kelvin. Default: |
Output Arguments
|
Effective system-noise temperature in kelvin. The effective system-noise temperature is |
