(a) True

(b) False

I got this question during an online interview.

I'd like to ask this question from Sensivity Enhancement for NMR Spectroscopy in division Nuclear Magnetic Resonance Spectrometer of Analytical Instrumentation

Answer 1

The correct choice is (a) True

To explain: In order to have a long measuring time for increasing sensitivity, it is better to have several fast scans than a single slow scan. The sensitivity increases by the square root of a number of scans.
