[Urgent] Design a counter with using D FlipFlop
The question is :
Design a counter that counts pulses on line w and displays the count in the sequence 0,2,1,3,0,2, ... Use D FlipFlops in your circuit. i wanna ask how to design this circuit? What are the steps to design this circuit? and What is the answer of this question? the ans. of the expressions are D(input) of A = A XOR B and D(input) of B = not A?? thank a lot~ =] 
#2




Write a Truth Table
Columns A and B represent the current Qoutput state of each of the DFlipFlops Columns P and Q represent the next Qoutput state of DFlipFlops A and B respectively. When you present the next Qoutput state on the Dinputs, the sequence of states is: By inspection: P and Q could, of course, be any functions of two boolean variables, and the sequences would change accordingly. [Question] What sequence do you get if you swap the functions for P and Q? It's not rocket science after all, just boolean algebra.

That Boolean guy was WAY ahead of his time.
But I still think Boolean Algebra is weird stuff.

http://en.wikipedia.org/wiki/George_Boole and I think Tensor Algebra, Riemanian Manifolds, Fractal Geometry, and Stochastic Calculus are way more wierd and complicated. Just my opinion  I could be wrong. http://en.wikipedia.org/wiki/Tensor_algebra http://en.wikipedia.org/wiki/Riemannian_manifold http://en.wikipedia.org/wiki/Fractal http://en.wikipedia.org/wiki/Stochastic_calculus
