Noise figure: A measure that quantifies the amount of unwanted signal power that is present in a communication system relative to the desired signal power. In simpler terms, it tells us how much of the signal is wasted due to unwanted sources.
Example: If a communication system has a noise figure of 3, it means that 3% of the signal power is lost due to unwanted sources. This means that the desired signal power is 97% of the total power in the system
