Fire Tragedy

I saw a fire tragedy in our 6 stored building on last Sunday, 13 June 2010. We all member in our building was in big treble when we know about the fife. I was in bathroom for have a baths. I am going to see what is happening. I tried to go the place where the fife start but i can't go there because of the key of that room were not found. I am trying to broke the lock but the heavy smoke made my work difficult. Then i am hit on to the glass of the windows for the smoke out of the room. The the people of our mohalla (area) came to help. Meantime a unknown man call the fire service. Within few minutes the smoke fully covered up to 2 floor. But lucky we can manege without major damage. Two people injured. Unfortunately one of them is me. Although i injured but i am happy for no major damage. Thanks God.

Today my favorite teem Argentina start their World Cup 2010 mission by winning a match with Nigeria. But it should be 4-0. The Argentina's players control whole time accept few counter attacks. Messi is today's hero for Argentina because he played superb today. Messi made few opportunities to score but Nigerian goal keeper safe by wonderful attempt. Congrats Argentina and best wishes for their next match.

Digital Signal Processing Lab Experiment

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.

Digital Signal Processing Lab Experiment 2

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.

Daffoid Institute Of IT

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.
