dBm

Consider the Friis' transmission equation $P_R = (P_T G_T G_R \lambda^2)/(4\pi D)^2$, where $P_R$ and $P_T$ are the received and the transmitted powers, respectively. $G_T$ and $G_...

Let the relevant bandwidth (B) of a digital communication system be 1 MHz and $kT = -174 \text{ dBm/Hz}$, where k is Boltzmann's constant and 'T' is equivalent noise temperature of...
