What kind of circuits?

Electrical?

Circuits Like this


A. PROBLEM STATEMENT
Design a priority encoder circuit. The circuit will have four inputs (P3, P2, P1 and P0) and two outputs (C1 and C0). The four inputs represent 4 pushbuttons and the outputs represent the binary code of the highest priority pushbutton that has been pushed. Pushbutton 3 has the highest priority and pushbutton 0 has the lowest priority. Since at least 1 pushbutton is active at all times the first row in your truth table where all 4 pushbuttons are 0 should have donít care output for C1 and C0.
EXAMPLES
1. Pushbuttons 2 and 0 have been pushed. This represents the row 0101 in the truth table. The output will be 10 (binary code of 2 since pushbutton 2 has a higher priority than pushbutton 0).The output 10 indicates that C1 = 1 and C0 = 0.
2. Pushbuttons 3, 1 and 0 have been pushed. This represents the row 1011 in the truth table. The output will be 11 (binary code of 3).

B. TRUTH TABLE
P3 P2 P1 P0 C1 C0
0 0 0 0
0 0 0 1
0 0 1 0
0 0 1 1
0 1 0 0
0 1 0 1
0 1 1 0
0 1 1 1
1 0 0 0
1 0 0 1
1 0 1 0
1 0 1 1
1 1 0 0
1 1 0 1
1 1 1 0
1 1 1 1
C. K-MAPS OF C1 AND C0.

D. MINIMIZED SOP EQUATIONS (1 FOR C1 AND 1 FOR C0)
C1 =
C0 =
E. You will use "Digital Works" to draw the MINIMIZED circuit and simulate the outputs (C1 and C0). Use AND, OR, Not gates as needed. Your circuit should be saved to a disk and named yourlastnameEXP2.dwm
F. Extra credit (5 points) draw another MINIMIZED circuit for the two outputs C1 and C2 using only NAND gates. This is optional. If you complete this part name it yourlastnameExp2Ex.dwm

Complete Parts B, C and D of this document, save it and zip it with the YourlastnameExp2.dwn file and YourlastnameExp2Ex.dwn and put the zip file in the dropbox under Digital Works 2.Competed Assignment is due by
October 5, 2009



I know no Homework questions but I just need help...I do not need someone to complete it unless they want too.

Sorry, I can't help you with that. I don't have the time to learn how everything works.

Besides, it depends on what each one is connected to. I didn't read it in depth, but I'm pretty sure I'd have to look at a diagram.

Oh, you're drawing the diagram. Hmmm... I'd have to think about this later. Maybe sometime later this week. Do you have a specific algorithm you're using to determine the binary values of C0 and C1? Are they seperate or what? I'm a little confused.
