SUMMARY
The output noise power (No) is calculated using the formula No = k(Ts + Te)BG, where k is the Boltzmann constant, Ts is the system temperature, Te is the equivalent noise temperature, B is the bandwidth, and G is the gain. When expressing noise power in dB or dBm, the calculation involves using 10Log10(Value) for dB and 10Log10(P/P0) for dBm, where P is the power and P0 is 1 mW. It is essential to use dBm for noise power calculations to ensure accurate representation.
