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.

Answer:

Your answer should be C

because in they will protect the data base from virus.

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;  

}

Answer: Use an Ethernet cable

Explanation:

Since the person will need to build out the networking for a small local business and wants to pull home runs to each of the devices after buying a core switch, the type of cabling that will be used to connect the network is an Ethernet cable.

An Ethernet cable is known to be the commonest network cable that's used on a wired network. The cable is required to connect the wired devices together to local network which is then vital for file sharing and Internet access.

Answer:

Tag = 1

Index = 5

Block offset = 2

Explanation:

From the given information:

The main memory bits(MM) = 221

number of block in the cache = 64 blocks

Block size = 4B

Recall that;

MM = log (memory size)

Thus;

main memory bits = log (221)

= 8 bits

Since this is a 2-way assoicative set;

the number of set in each cache = block size/2

64/2  = 32

Now, the index bit = log( no of set in each cache)

= log(32)

= 5 bits

Also since block size = 4B;

the block offset = log(4) = 2 bits

As such, tag = main memory bits - (index bit + block offset)

tag = 8 -(5 + 2)

tag = 8 -7

tag = 1

Answer:

b. In HTTP tunneling, some protocols travel inside HTTP traffic.

Explanation:

a. HTTP is not a stateful protocol. It is a stateless protocol since the receiver is not allowed to store the state from previous requests. In other words, there is no need to keep track of the session information or status. Other examples of stateless protocol are UDP (User Datagram Protocol) and DNS (Domain Name System).

b. In HTTP tunneling, some protocols travel inside HTTP traffic. HTTP tunneling allows two devices to be connected together using network link with or without restrictions such as firewalls and access control lists. One way of implementing this HTTP tunneling is by using the regular HTTP methods such as POST, GET, PUT and DELETE.

In other words, HTTP tunneling allows certain protocols travel inside HTTP traffic.

c. HTTP has not been replaced with IPV6. They are different protocols performing different functions. IPV6 is an internet protocol addressing scheme invented to replace its predecessor IPV4.

d. HTTP was not developed by AI Gore. It was developed by Tim Berners-Lee and his team.

Answer:

1. MOV CX, [BX+DI]

2. MOV AX, ARRAY[CX]

3. MOV BX, [CX+DI+6]

Answer:

There is no need to make an algorithm for this simple problem. Just add the two numbers by storing in two different variables as follows:

Let a,b be two numbers.

c=a+b;

print(c);

But, if you want to find the sum of more numbers, you can use any loop like for, while or do-while as follows:

Let a be the variable where the input numbers are stored.

while(f==1)

{

printf(“Enter number”);

scanf(“Take number into the variable a”);

sum=sum+a;

printf(“Do you want to enter more numbers? 1 for yes, 0 for no”);

scanf(“Take the input into the variable f”);

}

print(Sum)

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.

Answer:

Following are the response to the given question:

Explanation:

They are already talking business to business collects in which we are calling the client for collecting whenever the products which we have purchased are overdue and overdue inside 30 days. About business criteria, we should ensure no other websites mostly on agent acting open up so that nobody can misuse it; we also have to know the correct revising and trying to run off all systems and therefore all apps are organ systems because then the critical business work time has would not get out of the way. This is about the security of information. The agents also are adequately taught in IT policy according to the demand of the company.

They soon come towards the area of risk, experience, and skill. All agents ought to have proper refresh sessions to fulfill GAP knowledge but also improve their abilities for 100 percent cent accuracy on TAT on every appeal. Your Agency's response.

There ought to be a right party connect. We must keep up with 80-20 RULE which means that we can easily acquire the bigger amount earlier than somehow investing whatever money for future production if we concentrate on TOP 20 Overdue Current Passengers.

When we add up the current sum owing as well as the amount due by both the end of the month, so we will subtract all promises that were made by the end of each month. You can readily deduce how long and how much money will be received by the end of each month, and how long this will be due by the end of each month.

The total danger which we imagine to be cash flow issues is when a company is close to collapse or even has a money problem, they are few risks that any company has.

To solve this RISK to money flow clients, we have to provide them a payment plan so that we could at the very least invest some cash in additional production. Besides offering customers a pay system, you truly cannot help.

Another key potential risk is the unrequired quantity on the accounts of the consumer. Underneath the U.S. government, it'll be a direct responsibility of the government if there is an unclear and unapplied amount which has lied to an account for even more than 4 years.

Therefore it does have to do about risk, skills, knowledge the safety of information.

Explanation:

Boolean logic refers to a theory of mathematics developed by the prominent British mathematician, called George Boole. In Boolean logic, all variables are either true or false and are denoted by the number "1" or "0" respectively; True = 1 or False = 0.

Also, Boolean logic allow users to combine keywords with Boolean operators (quotes, AND, OR, near/n) to give a more personalized and relevant search results.

There are five (5) main Boolean Algebraic properties and these includes;

I. Commutative property: it applies to both multiplication and addition.

II. Associative property: it applies to both multiplication and addition.

III. Distributive property: it is formed using the product of a sum.

IV. Complement property: it involves a variable and its complement.

V. Identity property:

In digital electronics, Boolean expressions are used to represent circuits which comprises of Boolean operations and as such simplifying any logic expression without changing or altering any of it's functionalities and properties based on given operations or variables.

Hence, Boolean Algebraic properties can lead to a simpler expression and thus a simpler circuit.
