ascentengineers -----> Very interesting to see their work( http://ascentengineers.org/ ) and the way they are generating their business. I believe that they can be succeed in their business with electronics and free software . Because the market for these two are growing very fast in kerala. They found out their first customers as the college students. Giving consultancy to them .... is really a business.

I find that these ascentengineers are very young. And the courage they taking is really amazing.

computer graphics is not as simple as I expected

I have seen video from National Programme on Technology Enhanced Learning about COMPUTER GRAPHICS. I confused that whether I was hearing a Mathematics class or computer graphics. Real mathematics is used to map bits from image to CRT( screen).

GATE EC2003 question

Ans :
Number of Mesh = B - N + 1 where B = No of Branches
N = number of Nodes
Node equation = N - 1
where N = number of Nodes

here B = 7 , N = 4

so minium number of equation need to analyze the circuit is = N - 1 = 3

Qu(2):

The Laplace transform of of i(t) is given by
I(s) = 2 / s(1+s)
As t --> infinity, The value of i( t) tends to


Ans:
Inverse of I(s) ,
I(s) = 2/s -2/(1+s)
i(t) = 2 -2(e^-t) because L(1) = 1/s and L(e^-t .1) = 1/(S+1)
As t --> infinity ,
==> i(t) = 2 -2/(e^infinity)
==> i(t) = 2 - 2/infinity
== > i(t) = 2 because 2/infinity is zero

This is the answer I got. I am not sure about 2/infinity . ,,...

i don't know these answers are correct or not .. I didn't get key for GATE these question.
