When a standard analog Butterworth lowpass filter of order n is transformed using the bilinear transform s = c z−1 z 1, we obtain a digital lowpass filter with a Butterworth transfer function h(z).
The bilinear transform is a common method for converting analog filters to digital filters. This process involves replacing the s variable in the analog filter transfer function with a z-transform variable using the bilinear transformation. The resulting transfer function in the z-domain can then be used to design a digital filter that approximates the analog filter response. The Butterworth filter is a type of lowpass filter that has a maximally flat magnitude response in the passband, with a gradual roll-off towards the stopband. By applying the bilinear transform to the analog Butterworth filter, we can obtain a digital filter with similar characteristics, allowing us to perform signal processing operations in the digital domain.
So, when designing a digital Butterworth lowpass filter, you first design the analog filter of order n and then apply the bilinear transform to obtain the transfer function H(z) for the digital filter.

The following are two different images that are encoded using the same algorithm. The images are each in a 5 by 5 grid of pixels where each pixel is black, white, red, green or blue.
The image on the left gets encoded and compressed down to 21 digits while the image on the right gets compressed down to 25 digits. Although the same algorithm was used to encode and compress these images, why are the end results a different length?
The algorithm was probably used improperly in the image on the right, causing it to be a longer length than it should have been.
Because this is a lossy compression, sometimes information is lost during the compression.
The amount of size reduction from compression depends on the amount of redundancy in the original data.
The image on the right uses more colored squares and therefore requires more digits to represent the pixels.
Answer: The amount of size reduction from compression depends on the amount of redundancy in the original data.
The reason why the end results have a different length is because: C. The amount of size reduction from compression depends on the amount of redundancy in the original data.
What is a lossy compression?A lossy compression is also referred to as irreversible compression and it can be defined as a type of data encoding (data compression algorithm) in which the data in a file such as an image, is removed by using inexact approximations, in order to reduce the amount of size of a file after decompression.
Since the same algorithm was used to encode and compress these images, the reason why the resulting images have a different length is simply because the amount of size reduction from compression depends on the amount of redundancy in the original image file (data).

In a series circuit, resistance is?
Answer:
In a series circuit, the total resistance is equal to the sum of all resistances.
Explanation:
The same current passes through each resistor, so each resistor does its job as you would expect.
For Example:
a series circuit has a 2 Ω (ohm) resistor, a 5 Ω resistor, and a 7 Ω resistor. The total resistance of the circuit is 2 + 5 + 7 = 14 Ω.

Which letter shows the ball when it has the maximum kinetic energy
Answer:
D.
Explanation:
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules. M represents mass measured in kilograms. V represents velocity measured in metres per seconds square.Generally, when the final velocity at which a physical object moves is equal to zero (0), then it possess maximum kinetic energy.
Hence, the letter which shows the ball when it has the maximum kinetic energy in the graph attached is D.

1. Visual design and font/background are both essential and considered vital for the success of a web. If you are the developer, which of the two will you be focused on?
Answer:
As a developer, I'd be focused on the two starting with the front end.
Explanation:
A front-end developer simply is a user-end or client-side developer. A front-end person in web design is responsible for how a website looks and feels like, essentially, the websites' users first impression.
This is a huge task and can be very daunting even for the best developers. Whilst the back-end or the engine of a website is critical and indispensable, it is important for a developer to master the principles of front-end development first as that gives him a better perspective as to how they can better create and configure a matching or suitable back end.
Most if not all are designed to achieve a particular purpose e.g.
Increase salescommunicate informationtrainingelicit information etcThe ease with which the user is able to interact with the website will determine the extent to which the purpose of the website is achieved.
Some of the qualities of a great user interface the front end developer must keep in mind are:
Clarity Conciseness Familiarity EfficiencyConsistency AttractivenessBack-end has to do with the part of the website called the server.
In addition to the server, there are two other critical components of the back-end of the website:
Application and Database.Together, these three contribute to ensuring that you have a functional website. The server, application and database, all control what happens on the front end and results in what the user will see via the browser.
There are many high-functioning websites today that have very poor interfaces. A poor interface is a guarantee that people will spend less time on the website.
Conclusively, both ends are indispensable, as with most things, however, one should seek to understand how the user thinks and feels in relation to how they like to use a website before doing into the back-end to make that possible.

At the end there should be 8 balls on each corner. function start(){ for(var i = 0; i < 5; i++){ ballSet(); wallRun(); turnLeft(); } function wallRun(){ while(frontIsClear()){ move(); } } function ballSet(){ putBall(); } }
Answer:
The program only runs 5 five since the for loop statement is limited to loop only five times.
Explanation:
In programming, a for-loop statement is used to repeat a collection of events a definite number of times. The number of loops is specified and compared with a variable to execute a block of code.
The for-loop statement in the code above declares and initializes a variable "i" to zero, runs the block of code, and increments by one if it is less than 5.
To make it run eight times, the value five should be changed to 8 instead.
Answer: you have to change the 5 to 8 since its telling you to do it 8 times
Explanation: for(var i = 0; i < 5; i++) should be for(var i = 0; i < 8; i++)
What is the result of the following code fragment?
BigInteger a = new BigInteger ("10");
BigInteger b = new BigInteger ("25");
a.multiply(b);
a.add(b);
System.out.println(a);
A. 10
B. 35
C. 250
D. 275
Answer:
D
Explanation:
I don't know the language, but it is clear what is going on.
It looks like you are defining a value for a in both commands.
a.multiply(b); looks like you take the value in a (which is 10) multiply it by 25 and put the result back in a. So so far we have 10 * 25 = 250
Note the next command
a.add(b)
looks like you take the current value in a(which is now 250)
and put the value of b (which has not been changed. It is still 25) and put that in a (which is 250).
The result is 250 + 25 = 275
The answer is D. Since I only understand the logic, if this answer is wrong, I wish you'd leave a note.
1. Light of wavelength 900x10-9 m is emitted by a source. What is its frequency?
therefore the frequency = 6×10^14
The frequency of the light is "[tex]6\times 10^{14}[/tex]".
Given values:
Wavelength,
[tex]\lambda = 900\times 10^{-9} \ m[/tex]
As we know the formula,
→ [tex]Frequency = \frac{C}{\lambda}[/tex]
By substituting the values, we get
→ [tex]= \frac{3\times 10^8}{900\times 10^{-9}}[/tex]
→ [tex]= \frac{10^8}{300\times 10^{-9}}[/tex]
→ [tex]= 6\times 10^{14}[/tex]

A loan of $12000 was borrowed from the bank at 14% per annum calculate the interest on the loan at the end of the first year ?
Answer:
lmasjsjsjssjjssjjssjsjjsksakkalaaooaa
Loan borrowed = $12,000
Percentage of interest on the loan per annum = 14%
We know that :
[tex]\color{hotpink}\tt \: Simple \: interest = \color{plum}\frac{principal \times rate \times time}{100} [/tex]
In this case :
principal = $12000rate = 14%time = 1 yearSimple interest at the end of the first year :
[tex] = \tt \frac{12000 \times 14 \times 1}{100} [/tex]
[tex] = \tt \frac{168000}{100} [/tex]
[tex]\color{plum}\tt = \$1680[/tex]
Thus, interest = $1680
Therefore, total interest on the loan at the end of one year = $1680
