If an audio signal is to be coded, either for compression or for digital transmission, it must undergo some form of quantization. Most often, a general technique known as vector quantization is employed for this task, but this technique must be tailored to the specific application so it will not be addressed here. In this assignment, we will observe the effect of uniformly quantizing the samples of two audio signals.
a) Record your voice for 4 seconds and play it again using predefined MATLAB audio functions.
b) Use your Uquant function to quantize each of these signals to 7, 4, 2 and 1 bits/sample.
c) Listen to the original and quantized signals and answer the following questions using the comments in the same MATLAB file:
1- For each signal, describe the change in quality as the number of b/sample is reduced?
2- For each signal, is there a point at which the signal quality deteriorates drastically?
3- At what point (if any) does it become incomprehensible?
4- Which signal's quality deteriorates faster as the number of levels decreases?
5. Do you think 4 b/sample is acceptable for telephone systems? ... 2 b/sample?
d) Use subplot to plot in the same figure, the four quantized speech signals over the index range 7201:7400.

In this lab, you complete a C++ program that swaps values stored in three int variables and determines maximum and minimum values. The C++ file provided for this lab contains the necessary variable declarations, as well as the input and output statements. You want to end up with the smallest value stored in the variable named first and the largest value stored in the variable named third. You need to write the statements that compare the values and swap them if appropriate. Comments included in the code tell you where to write your statements.InstructionsEnsure the Swap.cpp file is open in your editor.Write the statements that test the first two integers, and swap them if necessary.Write the statements that test the second and third integer, and swap them if necessary.Write the statements that test the first and second integers again, and swap them if necessary.Execute the program by clicking the "Run Code" button at the bottom of the screen using the following sets of input values.101 22 -23630 1500 921 2 2Provided code:// Swap.cpp - This program determines the minimum and maximum of three values input by// the user and performs necessary swaps.// Input: Three int values.// Output: The numbers in numerical order.#include using namespace std;int main(){ // Declare variables int first = 0; // First number int second = 0; // Second number int third = 0; // Third number int temp; // Used to swap numbers const string SENTINEL = "done"; // Named constant for sentinel value string repeat; bool notDone = true; //loop control // Get user input cout << "Enter first number: "; cin >> first; cout << "Enter second number: "; cin >> second; cout << "Enter third number: "; cin >> third; while(notDone == true){ // Test to see if the first number is greater than the second number // Test to see if the second number is greater than the third number // Test to see if the first number is greater than the second number again // Print numbers in numerical order cout << "Smallest: " << first << endl; cout << "Next smallest: " << second << endl; cout << "Largest: " << third << endl; cout << "Enter any letter to continue or done to quit: "; cin >> repeat; if (repeat == SENTINEL){ notDone = false; } else { cout << "Enter first number: "; cin >> first; cout << "Enter second number: "; cin >> second; cout << "Enter third number: "; cin >> third; } return 0;} // End of main function

Following are the code to the given question:

#include <iostream>//header file

using namespace std;

int main()//main method

{

int first = 0,second = 0,third = 0;//defining integer variable  

int temp; //defining integer variable

const string SENTINEL = "done"; // defining a string variable as constant  

string repeat;// defining a string variable  

bool notDone = true; //defining bool variable

cout << "Enter first number: ";//print message

cin >> first;//input value

cout << "Enter second number: ";//print message

cin >> second;//input value

cout << "Enter third number: ";//print message

cin >> third;//input value

while(notDone == true)//defining a loop to check the value  

{

if(first > second)//use if to compare first and second value

{

int temp = first;//defining temp to hold first value

first = second;//holding second value in first variable

second = temp;//holding temp value in second variable

}

if(second > third)//use if to compare second and third value

{

int temp = second;//defining temp to hold second value

second = third;//holding second value in third variable

third = temp;//holding temp value in third variable

}

cout << "Smallest: " << first << endl;//print smallest value

cout << "Next smallest: " << second << endl;//print Next smallest value

cout << "Largest: " << third << endl;////print Largest value

cout << "Enter any letter to continue or done to quit: ";//print message

cin >> repeat;//holding string value

if (repeat == SENTINEL)

{

notDone = false;//holding bool value

}  

else //else block

{

cout << "Enter first number: ";//print message

cin >> first;//input value

cout << "Enter second number: ";//print message

cin >> second;//input value

In this code, there's a Person class that has an attribute name, which gets set when constructing the object. Fill in the blanks so that 1) when an instance of the class is created, the attribute gets set correctly, and 2) when the greeting() method is called, the greeting states the assigned name. mtino 1-class Person: 2 - def __init__(self, name): self.name = def greeting(self): # Should return "hi, my name is " followed by the name of the Person. return Run 8 # Create a new instance with a name of your choice 9 some_person = 10 # Call the greeting method 11 print (some_person. ) 12 Press ESC to exit the code block at any time

Answers

Answer:

Explanation:

The following code is written in Python. It creates a Person class and creates the constructor which takes in the name of the person for that instance, as well as a greeting method which outputs the desired "Hi, my name is" string with the name of that person. The output of the code can be seen in the attached picture below. I have created a person object called John and called the greeting method so that you can see the output.

class Person:

   name = ''

   def __init__(self, name):

       self.name = name

   def greeting(self):

       print('Hi, my name is ' + self.name)

The code containing the Person class definition and the greeting is found in the attached image

The Person class has a single instance field name that stores the name of the person.

The instance initializer, __init__, accepts an argument, name, and saves the value in the name attribute of the Person class.

The Person class also has a greeting method that is called by the main code segment. The main code segment creates a Person object, and calls it in the print function to display the greeting with the person's name.

Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. calcPyramidVolume() calls the given calcBaseArea() method in the calculation.

Answers

Answer:

The method in C++ is as follows:

double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){

   double baseArea = calcBaseArea(baseLength, baseWidth);

   double volume = baseArea * pyramidHeight;

   return volume;    

}

Explanation:

This defines the calcPyramidVolume method

double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){

This calls the calcBaseArea method to calculate the base area of the pyramid

   double baseArea = calcBaseArea(baseLength, baseWidth);

This calculates the volume

   double volume = baseArea * pyramidHeight;

This returns the volume

   return volume;  

}

Write a program to sort the (name, age, score) tuples by descending order where name is string, age and score are numbers. The sort criteria is: 1: Sort based on name 2: Then sort based on age 3: Then sort by score The priority is that name < age < score. If the following tuples are given as input to the program: [('John', '20', '91'), ('Jason', '21', '85'), ('Jony', '17', '91'), ('Johny', '17', '93'), ('Tom', '19', '80')]\

Answers

Answer:

The program in Python is as follows:

from operator import itemgetter

m = int(input("Number of records: "))

print("Name, Age, Score")

my_list =[]

for i in range(m):

   user_details = input()

   my_list.append(tuple((user_details.split(","))))

my_list.sort(key =  itemgetter(0, 1, 2))        

print("Sorted: ", my_list)

Explanation:

This imports the operator function from itemgetter

from operator import itemgetter

This gets the number of records, m

m = int(input("Number of records: "))

This prints the format of input

print("Name, Age, Score")

This initializes the list of tuples

my_list =[]

This iterates through m

for i in range(m):

This gets the details of each person

   user_details = input()

This appends the details to the tuple

   my_list.append(tuple((user_details.split(","))))

This sorts the tuple

my_list.sort(key =  itemgetter(0, 1, 2))        

This prints the sorted tuple

print("Sorted: ", my_list)
