How can I convert dB uV / sqrt(Hz) to amplitude (V) ?

Hi everyone,

I need your helps.

I have the values in the form of dB uV / sqrt(Hz) for each frequency (Hz) and I have to convert these dB uV / sqrt(Hz) values to amplitude (V). How can I do this ?


Thanks

hi OmerN

for a start this formula isn't for a single frequency, the Hz refers to the freq bandwidth that you are interested in measuring the noise

have a look at this video and see if it helps ....

You calculate a total noise level by integrating the output noise density (V2/Hz) over the system bandwidth and calculating the square root.
