Hello.

I was wondering how I calculate the noise a circuit injects into a signal I wish to read? It's a circuit consisting of a sensor, resistors, capacitors, differential amplifiers and such alike. How do I calculate the noise the whole circuit makes? Do I have to calculate for each Component or is there a faster way to do that? Look at the frequency spectrum or the power spectrum? Look at the wave signal or what?

Thanks!
