Formula's of S and S Posted by Soman Khan , Sunday, March 28, 2010 at 6:06 AM, in

Formulas written by sir Junaid in class of Signal and systems on Thursday,25th of March are written below

cos(X + Y) = cosX cosY - sinX sinY
cos(X - Y) = cosX cosY + sinX sinY
sin(X + Y) = sinX cosY + cosX sinY
sin(X - Y) = sinX cosY - cosX sinY 

cos ²X +sin ²X=1

cos(2X)= cos ²X -sin ²X
cos(2X) = 1 - 2sin ²X

cos(2X)= 2cos ²X - 1 

sin(2X) = 2 sinX cosX
sin ²X = (1 - cos(2X))/2
cos ²X =(1 + cos(2X))/2

sin(90-A)=cosA

cos(90-A)=sinA

Happy Pakistan day Posted by Soman Khan , Monday, March 22, 2010 at 10:20 PM, in

Hello dear friends I wish you a very very happy Pakistan day. Today is the 70th birthday of Pakistan resolution. Its time to pay homage to ancestors who scarified their lives for us. I salute them all. This is a dedication from me to all of them.

I will put in my box

A giant greenish-blackish tree
Sparks from a pistol
The cries of thousands of people

I will put in my box

The founder of Pakistan
The books of the year
The uniforms of people who died in wars

I will put in my box

A beautiful day of Independence
A taste of victory
Sounds of firecrackers

I will put in my box

Celebration of our heroes
Sights of our people happy
A view of my grandfather’s garden–he died studying those books

My box is made of brown, old papers, papers of Independence
I will celebrate my country in my box with my family.
I will play cricket in my box forever!

Solution Manual for Signal and Systems Posted by Soman Khan , Sunday, March 21, 2010 at 7:24 AM, in

Hello friends I got the solution manual for signal and systems book. I got it from external source. And i don't know how accurate they are, but i still recommend you that get them downloaded and read them may be it help you in your studies. Study them thoroughly and one thing more to be mentioned here, download them on your own responsibility. Never claim about their accuracy, as i also get them from someone else. You can download these notes by clicking here. These notes worth 26Mb in size so guys you have to wait a little for them to be downloaded. If any of you finds difficulty in downloading or link broken result, comment here or mail me.
