Signals, spectra, resonance, etc.

[Void123]

Quick question:

I keep seeing the following terms in my reading on nuclear magnetic resonance:

- Spectral linewidth
- Spectral bandwidth
- Signal bandwidth

Are these all qualitatively different terms? Or are they more or less referring to the same thing?

Yes, they are synonyms; see http://en.wikipedia.org/wiki/Spectral_linewidth
