Design Even Number Generator with 4 Bit Counter

Click For Summary

Discussion Overview

The discussion centers around designing an even number generator using a 4-bit counter without employing flip-flops. Participants explore various methods and clarify the distinction between different types of even number generators.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests counting up and adding a zero bit after the count to generate even numbers.
  • Another participant proposes that left shifting a number is equivalent to multiplying by 2, which could be a straightforward method to create even numbers.
  • A question is raised about whether the goal is to create a simple even number counter or a pseudo-random even number generator, indicating a significant difference in approach.
  • There is a mention of writing boolean logic equations to develop a circuit that outputs even numbers based on input, but this is noted to ultimately reduce to a left shift operation.

Areas of Agreement / Disagreement

Participants express different interpretations of the task, with some focusing on a straightforward counting method while others consider the implications of randomness in the generator design. No consensus is reached on the specific requirements or methods to be used.

Contextual Notes

The discussion does not clarify certain assumptions about the type of even number generator desired, nor does it resolve the mathematical implications of the proposed methods.

how can i design an even number generator with a 4 bit counter without using any flip-flop , Using only 4 bit counter?

have it count up, then add a zero bit after the count.
 
Left shift one (as anorlunda says) is the same as multiplying by 2, which is the simplest way to create even numbers.

Were you looking for something different than this?

You can write boolean logic equations to develop a circuit that outputs 2 when you input 1, etc, but it will just reduce to a left shift.

do you mean an even number generator (a counter), or a (psudo) random even number generator (jumps around to different numbers)?

There is a big difference
