hey guys , i would like to share with you a problem:
i have 7 bits num, all i need to check how much "1" i got in the num.
exmple: if the num is: 1001101 i should output 100.

i solved the prob , by trying again and again but i couldn't understand why this is true, or how next time, ill do it better, and have a straight way to solve it.
the solution is attached.

if someone can walk with me step by step whats the idea and the princple that i need to walk through it will be more then great!

thx!!!!!

So, let me get this straight, YOU solved this problem, but you have no idea how YOUR solution works and you need someone to explain to you how YOUR solution works.

How did you manage to come up with this solution that you claim YOU came up with? Did you just randomly connect a bunch of full adders together until you happened upon a circuit that just happen to mysteriously do what you wanted to do?

Since you are so lucky at combining circuit components at random to produce a desired result, how about just opening a text file and randomly hitting keys. It shouldn't take long before you'll just happen to type out the correct description of how it works.

Sounds like homework.
I'll give your question an A+ for originality in trying to get us to solve your problem.

You're getting ready for a work interview by asking others to explain to you how a simple circuit that you claim YOU came up with works?

At least the post-interview decision process won't take long.

Perhaps if you could explain how YOU came up with that circuit, the very process of doing so will shed light on how it works.

Unless, of course, the method by which YOU came up with it involves that copier you mentioned.

Sorry but you still seem less than truthful.
How is it that this particular problem solution is needed for your "work interview"?

You look simply dangerous!

Cool circuit. What software did you use to draw that?
