Homework Statement Design [/B]:2-bit count-down counter; with two flip-flops and one input Homework Equations When input = 0, the state of the flip-flops does not change. When input = 1, the state is 11, 10, 01,11, and repeat. The Attempt at a Solution Start with truth table, then...

Homework Statement AC'D+ AB'D + BCD' + A'BC 2. Homework Equations The Attempt at a Solution Would I start by inverting all the inputs? Would there be 3 Or's to this? I get from the truth table, to simplifying expressions with k-map, but I don't know how to turn it into a circuit. Can someone...

Will I have three Or's in that expression?

Can you help me set one up, preferably a harder one? AC'D+ AB'D + BCD' + A'BC

Thanks for your help, appreciated greatly! I never turned a big expression like B'CD + A'BD + BCD + ABD + DB into a circuit before. Do I take the expressions for w,x,y,z and put them altogether?

Here's a look at my K-Map and expressions. Now I take the expressions and build the circuit in a testing program?

I uploaded another.. I don't understand how to get the highs in the x,y,z outputs though, what am I looking at to form the logic?

Okay I uploaded a picture. I put the 1's in the K-map after and now i need to form the expression. I build the circuit from the expression then?

Homework Statement Design a combinational circuit that multiplies two numbers together, and outputs the result. Homework Equations The biggest product will be 3 * 3 = 9. Four bits to represent the product. 0: 00 1: 01 2: 10 3: 11 I need a 4 bit register for the outputs The Attempt at a...
