(a) Interpretation: The type of noise that is reduced by a high-pass filter needs to be determined. Concept introduction: Chemical analyses are related with two types of noise which are chemical noise and instrumental noise. Chemical noise is due to reasons that affect the chemistry of the system being analyzed. Instrumental noise is components of the instrument. There are four types of instrumental noise and they are thermal noise, shot noise, flicker noise and environmental noise. Filters are used to reduce these noises.

Chapter 5, Problem 5.5QAP
Interpretation Introduction

(a)

Interpretation:

The type of noise that is reduced by a high-pass filter needs to be determined.

Concept introduction:

Chemical analyses are related with two types of noise which are chemical noise and instrumental noise. Chemical noise is due to reasons that affect the chemistry of the system being analyzed. Instrumental noise is components of the instrument. There are four types of instrumental noise and they are thermal noise, shot noise, flicker noise and environmental noise. Filters are used to reduce these noises.

Interpretation Introduction

(b)

Interpretation:

The type of noise that is reduced by a low-pass filter needs to be determined.

Concept introduction:

Chemical analyses are related with two types of noise which are chemical noise and instrumental noise. Chemical noise is due to reasons that affect the chemistry of the system being analyzed. Instrumental noise is components of the instrument. There are four types of instrumental noise and they are thermal noise, shot noise, flicker noise and environmental noise. Among them flicker noise and environmental noise are frequency dependent thermal noise and shot noise are frequency independent. Filters are used to reduce these noises.
