// Given Data
G_rx = 97; // Rx gain in dB
Bn = 5*10^6; // Bandwidth in Hz
To = 300; // temperature in kelvin
K = 1.38*10^-23; // Boltzmann constant in J/k
n = -3 // o/p noise power in dBm
// calculations
Pn_dB = n-G_rx // input noise power
Pn = 10^(Pn_dB/10)*10^-3 // converting from dBm to watts
// Pn = KToBnF;
F = Pn/(K*To*Bn) // Noise Factor
T = To*[F - 1] // Equivalent Noise Temperature
// Output
mprintf('Equivalent Noise Temperature = %d°K',T );
