I'm a CompE over at the University of Illinois... here's the problem, hopefully someone can help...

I have the implement the following three functions using only three 4x1 MUXs and an inverter(optional).

F(x,y,z)=AND(M1,M4,M6)
G(x,y,z)=OR(m1,m3,m5)
Z(x,y,z)=x XOR z

Note: S1S0 of the MUXes must be y and z.

Thanks for any help at all.

Oh, I also need to implement the same functions using only a ROM for another part of the problem, and another part of the problem calls for implementing the same fucntions using a PLA with four product terms(no other components avialable). Thanks alot nerds.

Remind me again why we should be doing YOUR homework - especially after insulting us?
Link Posted: 9/27/2005 3:24:48 PM EDT
Do you own fucking homework. If you can't, accept the F.

You'll make a great engineer.

Do the world a favor and change your major to psychology.

I get the g and h outputs, but I can't get f.... I've implemented the same damn circuit four times and its still not coming to me...

How about thinking about it instead of looking for a freebie online.

Nice engineering skills, asshole.

Explain to us how you got accepted into one of the best engineering programs in the country and cannot do this stuff?

With all due respect go fuck yourself... I HAVE BEEN THINKING ABOUT IT... for the last fucking three hours, this is a long shot I know, I've tried calling a bunch of people I know in the same class and we all have the same fucking problem.

Then ask the teacher for help outside of class. Quit looking for someone to give you free answers. Go to a study group, talk to the teacher, the TA, etc.

With no respect intended, eat shit and die.

One of the biggest universities in Illinois and you can't do your homework

I should go to school tomorrow(I go to community college, Moraine Valley specifically) and maybe I should ask the engineering students if they can do their homework.

I goto fricken review sessions every week thursdays 5-6:30 and I understand what I need to do to get this, I'm looking for a hint, anything... I just can't get this, I'm fucking stuck and frustrated. The jealously coming from some people on this board is hilarious though...

Very good actually...thanks for asking. I love it here. You can't beat a school that's close to home(I live 1.8 miles away), cheap, and has good classes and profs to boot.

IIRC fellow IL crew member CKmorley went there, and he can attest to how good it is.

As far as how intensive the classes are, I can't comment on engineering, but the thing you gotta realize is that community colleges aren't stupid, neither are the students that go there. It's actually a good alternative to shipping yourself away. I'd reccomend it.

Dude, if you can't do this problem you would never pass an interview that I gave you.
This is intro to digital logic level. You better shoot for management.

MUX.. multiplexer? X amount of 'data' in Z amount of data out?

You'll want to look up something called a Univeral Logic Module. It's just a technique of using a mux (multiplexor) to implement logic functions.
