IT133 – Week 3 Assignment

IT133 – Week 3 Assignment 4B/5B is a block encoding system that breaks up long strings of zeroes and ones but does not increase the frequency bandwidth by breaking them up in four-bit sequence. Table 1 shows each block of four bits replaced by a block of five bits. Due to this, there cannot be more than one leading zero and two trailing zeros. This means that the resulting bit stream has no more than three consecutive zeros (Figure 1). This bit stream is transmitted using non-return to zero inverted (NRZI) method and is used in 100BaseTX (Fast Ethernet) networks ...

Line 1: clc command clears all data in the command window.

Line 2: clears the system memory, removes the data from workspace. Line 3: closes all the files. Line 4: leaves the line blank. Line 5: forms variable N and fills it with the data from the file “note.txt”. Line 6: forms variable E and fills it with the data from the file “elem.txt”.

Line 7: leaves the line blank.

Line 8: returns NN variable, which is the length of the largest array dimension in N. Line 9: returns NE variable, which the length of the largest array dimension in E. Line 10: leaves the line blank. Line 11: assgins the value 2.1∙106 to ...

Short – Term Investing

Introduction A treasury bill or a T-Bill is a short-term maturing promissory note, usually lasting for three months to one year. Nyawata (2012) asserts that the federal or national governments are the ones that issue T-Bills as their primary instruments of regulating the supply of money within the national economy, as well as raising funds for various government projects through open market operations. The central banks of the respective countries are the ones responsible for issuing and paying on T-Bills. According to Thau (2000) T-bills do not have any form of explicit interest, but they sell at a discount ...

Introduction

Play LOTTO Research Lotto game rules (https://www.national-lottery.co.uk/), then design and implement a Matlab programme to generate several sets of Lotto numbers according to the amount of money specified. The relevant information about the Lotto game rules taken from the National Lottery website are enumerated in the following bullet points:

Simply select six numbers from 1-59 or pick Lucky Dip for a random selection Choose how many lines to play The Matlab programme will operate the same way as the Lucky Dip feature of the website. The Matlab programme will randomly generate sets of six numbers from 1-59 that are ...

SORTING ALGORITHMS

INTRODUCTION Two sorting algorithms are studied in this paper: bubble sort and quicksort. Bubble sort is a comparison-type algorithm. It compares the elements of the array two at a time. It starts comparing from left to right of the array elements. The element with the greater value is placed on the right, and then compared to the next element. This is done until the largest element is placed at the end of the array. At this point, the largest sorted element is considered sorted, while the rest of the elements are unsorted. The algorithm is repeated for the remaining ...

1. The bode plot of the system is:

The zeros are located at:

f=0, 500 Hz

The poles are located at:

f=3.4, 50, 2120 Hz 2. Converting Hz to rad/s,

Zeros:

ωz1=0, ωz2=2π500=1000π

Poles:

ωp1=2π3.4=21.36, ωp2=2π50=100π, ωp3=2π2120=4240π 3. The form of the transfer function is: Hs=Kss+1000π(s+21.36)(s+100π)(s+4240π) Hs=j2.136=1=Kj2.136j2.136+1000π(j2.136+21.36)(j2.136+100π)(j2.136+4240π) 1K=7.47×10-5→K=13387

The transfer function becomes:

The monitoring of the Gigabit Passive Optical Networks (GPONs) is based on the optical coding (OC) technique and which is the most cost-effective monitoring technique. The performance of the OC technique relies on the design of the implemented hardware and on the design of the address code chosen. With an increasing number of GPON users, the address code selected must has the ability to support a number of code-words that are equal or larger than the available users. The main purpose for this research is to improve the GPON monitoring system using the OC technique. This research has developed ...
