WebFor thermal noise, its spectral density is given by N 0 = kT, where k is the Boltzmann constant in joules per kelvin, and T is the receiver system noise temperature in kelvins. The noise amplitude spectral density is the square root of the noise power spectral density, and is given in units such as /. See also. Noise-equivalent bandwidth WebSuch emissions from your own TX to your own RX at the RX frequency are referred to as receive band noise (we emphasized the RX frequency, because if it is not at the RX …
