Creating a 4-Cycle Counter in Digital Logic

Click For Summary

Discussion Overview

The discussion revolves around creating a digital logic counter that outputs a signal every fourth clock cycle. Participants explore the challenges of developing a truth table and state table for this counter design, particularly focusing on the difficulties faced by a newcomer to digital logic.

Discussion Character

  • Homework-related, Technical explanation, Exploratory

Main Points Raised

  • One participant expresses uncertainty about how to create a counter that outputs a 1 every 4th clock cycle and mentions difficulties with truth tables.
  • Another participant suggests that a truth table or state table would be a good starting point for the problem.
  • A participant shares their attempt at a truth table but indicates confusion regarding the next states and Karnaugh maps, noting issues with multiple values for the same state.
  • A later reply indicates that the participant found a solution to their problem without elaborating on the details.

Areas of Agreement / Disagreement

There is no consensus reached in the discussion, as participants express differing levels of understanding and approaches to the problem. The initial participant's confusion remains unresolved, while another participant claims to have found a solution.

Contextual Notes

The discussion highlights limitations in the initial understanding of truth tables and state transitions, as well as potential gaps in instructional support from the teacher and textbook.

Im not sure if this is the right place to post this but here's my question. I have to create a counter that outputs a 1 every 4th clock cycle. I can't make a truth table because it doesn't really make sense. I am a newb to digital logic and suck at it. Any one have any help.
Thanks

Moved to homework forums. And yes, a truth table or state table would be a good start...
 
truth table doesn't work

I tryed a truth table and i was having problems with it.
present Next state
Q1 Q0 | Q1 Q0
0 0 | 0 0
0 0 | 0 0
0 0 | 0 1
0 1 | 0 0

So when I make the Karnaugh maps will have two values for 0 0. My teacher didnt really go over this well and the book has no help. So I am stuck at this point. What am I doing wrong?
 
got the answer nevermind
