Chapter 4, Problem 4.18P
Interpretation Introduction

(a)

Interpretation:

Substitution of Mg2+ for yttrium ions in Y2O3 causes the point defect in Y2O3 structure. Changes required in structure to maintain charge balance are to be explained.

Concept Introduction:

Point defect can be defined as the missing of an atom from its crystal lattice or presence at irregular place in its crystal lattice. Point defects can be of many types such as self-interstitial atoms, interstitial impurity atoms, vacancies, and substitution atoms.

Interpretation Introduction

(b)

Interpretation:

Substitution of Fe3+ for magnesium ions in MgO causes the point defect in MgO structure. Changes required in structure to maintain charge balance is to be explained.

Concept Introduction:

Point defect can be defined as the missing of an atom from its crystal lattice or presence at irregular place in its crystal lattice. Point defects can be of many types such as self-interstitial atoms, interstitial impurity atoms, vacancies, and substitution atoms.

Interpretation Introduction

(c)

Interpretation:

Substitution of Li1+ for magnesium ions in MgO causes the point defect in MgO structure. Changes required in structure to maintain charge balance is to be explained.

Concept Introduction:

Point defect can be defined as the missing of an atom from its crystal lattice or presence at irregular place in its crystal lattice. Point defects can be of many types such as self-interstitial atoms, interstitial impurity atoms, vacancies, and substitution atoms.

Interpretation Introduction

(d)

Interpretation:

Substitution of Fe2+ for sodium ions in NaCl causes the point defect in NaCl structure. Changes required in structure to maintain charge balance is to be explained.

Please can you assist with the attached question please?
1. For v(t)=2Σn-[8(t-n) + 28(t-n-0.4)], determine (a) (10%) a figure of v(t); (b) (5%) period To; (c) (10%) Fourier series in Form III; (d) (5%) Fourier transform; (e) (5%) total power.
THIS IS NOT A GRADING ASSIGNMENT: Please only do lab 2.2 (bottom part of the first picture) For that Lab 2.2 do: *Part 1 (do the CODE, that's super important I need it) *Part 2 *Part 3 I also attached Section 2.5.2 which is part of the step 1 so you can read what is it about.   Thank you!
