hi all,

I am quite confused of the noise spec such as noise figure and root mean square noise voltage. And, how to measure them? Can you provide me some reference?

Thanks.
 

Noise Figure (NF) specifies how much additional noise ur system will contribute in addition to the input noise.
How to measure NF ..Please check maxim-ic Application note

Noise is random quantity..there rms value gives the measure magnitude of how a signal is varyingy. especially when it varies in positive and negative direction
