Chapter 5, Problem 5.8QAP

Interpretation Introduction

(a)

Interpretation:

The signal-to-noise ratio is to be stated.

Concept introduction:

The signal and noise are two components of instrument measurements. One component is the signal, which carries the information that is of interest to the scientists and another component is the noise which refers to the unwanted fluctuations of signals.

Interpretation Introduction

(b)

Interpretation:

The number of measurements required to obtain a $S/N$ of $10$ is to be stated.

Concept introduction:

The signal and noise are two components of instrument measurements. One component is the signal, which carries the information that is of interest to the scientists and another component is the noise which refers to the unwanted fluctuations of signals. For $n$ number of repetitions the signal to noise ratio is proportional to square root of number of repetitions.
