Receiver system-noise temperature
Compute System Noise Temperature
Calculate the system noise temperature of a receiver with a 300 K reference temperature and a 5 dB noise figure.
T = systemp(5,300)
T = 948.6833
NF — Noise figure
Noise figure in decibels, specified as a nonnegative scalar. The noise figure is the ratio of the actual output noise power in a receiver to the noise power output of an ideal receiver.
REFTEMP — Reference temperature
290 (default) | nonnegative scalar
Reference temperature in kelvins, 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.
