Hi!

I'm new here so I'm sorry if that post shouldn't get here.

As a IT student I have some Digital electronics lessons. The problem is that I don't and can't understand anything (I am graphic designer). I wish You could help me with some exercises. So, here are them, just 3 (I don't know Digital Electronic specifics terms so I'm sorry if I'll bad translate some words):

1. Make scheme of function f(x1, x2, x3, x4) = ∑(0,4,5,7,13(1,3,9,10,12)) based on multiplexer with 3-addresses inputs.

2. Make scheme of combination system which give logical 1 on the output, when the 4-bit number "N" (in Ex3 code) is prime. System must be based with use of NAND functors.

3. Make iterative combination system of 3-bit comparator with 1-block structure (like in the attached picture) based on NAND functors, when d = m = 0, r = 1.

I'm using Quartus.

I would appreciate Your help :)
