1) To synthesize the sequence x(n)=1,,1,2,2,3,3,2,1 for -2<=n<=5
Solution:
n=[-2:5];
x=[1,1,2,2,3,3,2,1];
plot(n,x,'o')
stem(n,x)
Write this on your MATLAB software and then you will see the graph.
2) To synthasize the expoonential impulse response x(n)=(0.9)^n for index values n=0,1,2, ..........,50
Solution:
n=[0:50];
x=(0.9).^n;
plot(n,x,'o')
grid
Write this on your MATLAB software and then you will see the graph.
3) Superimposing two plots for comparison (N.B.- Problem 1 & 2)
Solution:
y=exp(-n/10);
plot(n,y,'+');
hold on
plot(n,x,'o');
hold off
Write this on your MATLAB software and then you will see the graph.
4) To generate a complex valued exponential sequence
Solution:
x=exp((2+3j)*n);
subplot(2,2,1)
plot(n,real(x),'o');
subplot(2,2,2);
plot(n,imag(x),'o');
subplot(2,2,3);
plot(n,abs(x),'o');
Write this on your MATLAB software and then you will see the graph.
Yesterday i post about spy camera with a headline of "Be Aware, You May Be Catch Up!!" and it was in a belt. Now i am going to post another camera that is in watch.
I am disappointed by the work of Daffodil Institute of Information Technology. They offer course for web development and gives a detail course outline. Now they say that they can't cover the whole outline. They only cover PHP & My SQL. I am really very disappointed. It is not good for a highly popular institute. It is shame that they talk very much.
Be aware, you may be catch up!! Few days ago i find few article on hidden camera. This camera are set in such a place, you can't find that. They can capture your video & picture. And they can black mail. So be aware. Now i am giving the picture of the hidden camera.
Now our university lunch on semester result through SMS. If anyone wants to know the result just do following:
Exam: DIU RES 081-19-882

"What a batting!!! What a show!!! Incredible wicket given!!!" All this things do our idiots batsman. Now they are in a situation that if England want they have to batting again under follow on. After a super opening partnership of 126 they are all out in 216. Tamim Iqbal 108 of 216. And Bangladesh is trial by 203. If Bangladesh can score another 4 runs they can avoid follow on.
