FFT is the frequency domain representation. In can be shown in Simulink with blocks. These blocks graphically show the domain or x value plotted against the frequency or y value.

It's called city-block distance, because it is calculated as if on each pixel between your two coordinates stood a block (house) which you have to go around. That means, you can only go along the vertical or horizontal lines between the pixels but not diagonal. It's the same like the movement of the rook on a chess field.

Clinique is a skincare and cosmetics brand known for its dermatologist-developed products that emphasize allergy testing and fragrance-free formulations. Launched in 1968, it focuses on creating products suitable for a variety of skin types and conditions, promoting a personalized approach to beauty and skincare. Clinique's image is built around the principles of efficacy, simplicity, and inclusivity, appealing to consumers who seek reliable and gentle beauty solutions. The brand is also recognized for its iconic packaging and commitment to sustainability.

Iska matlab hai Six.

zeros makes a matrix of the specified dimension, filled with zeros.

BPSK Modulation can be done by using a multiplier. Digital data must be multiplied with the carrier frequency. In matlab simulink use a multiplier block to one input apply a sinusoidal generator & to the other a Pulse generator

3D get it!

No, an image formed in a mirror is unreal, because mirror reflects all the light rays off.

the gaussian filter is also known as Gaussian smoothing and is the result of blurring an image by a Gaussian function.

Below code generates unit step function

n1=-4;

n2=5;

n0=0;

[y,n]=stepseq(n0,n1,n2);

stem(n,y);

xlabel('n')

ylabel('amplitude');

title('unit step');

It results in a unit step whose value is 1 for time T>0.

Without image acquisition you have no image to process.

y^2=x^3-x+6

Yes.

Let us use an example:

x=1:10; % Data Set

z=1:20; % Range

y=x^2; % Equation

equation1=trapz(y,z) % This will integrate y over the range of z for your data

When integrating over a matrix:

x2=[ 1 2 3; 4 5 6]; % Matrix

y2=x*C; % Where c is any variable

equation2=trapz(y2);

% Will integrate over every column of your matrix and give you an array.

To read the value of a resistor:

Resistors are color coded, you can use the chart found below

And how accurate the values of resistors are is their tolerance, also found in the chart

Already saved file i.e, .PNG. Open the Photoshop Application , then go to file menu, and select the OPen, where u already saved file is .PNG select it click ok. it will in photoshop file .PNG the again go to file menu then click save as option the name it and format it as .GIF and click it save button.

It depends on the image editor. In Photoshop there's a option of "Place" under the "File" menu. Copy and paste sometimes works or drag and drop from a Windows Explorer (e.g. My Documents) window.

A=2; t = 0:0.0005:1;

x=A*sawtooth(2*pi*5*t,0.25); %5 Hertz wave with duty cycle 25%

plot(t,x);

axis([0 1 -3 3]);

The above code can generate sine wave using Matlab.

no way... use awgn function in matlab

There is various line coding schemes that can be used in Matlab including Manchester, polar, unipolar, and bipolar. The Matlab language allows you to write these codes in math-based notations making it easy to see solutions.
