# Need help with some basic stuff..

Helios
I have a really big test about digital electronics coming soon, and I got stuck on a really basic exercise, as usual

It's about MUX realization, I just had to miss that lesson and now I don't even know the basics.. damn!

Anyway,
I have this function: F(A,B,C,D) = A'(C'+B'D')+CD(A+B)

I have to realize this function using a 8-to-1 MUX, while the control inputs are A,C and D.

2nd, I have to realize the same funcion using a 4-1 MUX. I can select any control inputs, but I have to keep the minimum number of added gates.

help?

I don't think these are basic . I can't even understand these things.

Can ya tell me What topics are you talking about.
I like to read books on unknown things may be it will be something interesting.

I'm stuck on a MUX(a.k.a Multiplexer) related exercise...

I've missed the lesson about MUXes and DeMUXes, that's why I don't really know this material

Just a thought...

Of course you wouldn't understand a thing Helios had said if you don't know anything about Digital Electronic Systems as Helios has pointed out.

Anyways, Helios, are you a college student too? What's the course that you've been taking up?

I have 1 day left until the test,
I really want the answer for that problem I've posted...
