How do you calculate noise power bandwidth?
Thermal white noise power is defined by: N=kTB, where N is the noise power available at the output of the thermal noise source, k = 1.380 x 10-23 J/K is Boltzmann's constant, T is the temperature, and B is the noise bandwidth.
What is the bandwidth in the noise power?
Equivalent noise bandwidth is the bandwidth of a perfect rectangular filter that allows the same amount of power to pass as the cumulative bandwidth of the channel selective filters.
How do you calculate noise power?
The noise power from a simple load is equal to kTB, where k is the Boltzmann constant, T is the absolute temperature of the load (for example a resistor), and B is the measurement bandwidth.
How do you calculate noise power in dBm?
It is the output power per hertz that the source provides. To calculate the power that the source will have in a BW the No is added to the dB (BW). For example a -80 dBm/Hz amplified noise module with 1 GHz BW will have a minimum of -80 dBm/Hz + 10 log (1 GHz) = -80 dBm/Hz + 90 dB = +10 dBm.
