I am trying to plot a Noise Spectral Density from 10 kHz to 1 MHz. The Graph shows a cure which at 1 MHz the noise is 76 pV/rootHz. I am unable to understand that unit definition here. Becuase the unit Says that it is per root of Hertz it has 76 pV. Is that true? Should I apply a formula to convert it to frequency. Please let me know. I have attached an image.
Thanks in advance.
