Minimize the circuit for this expression

Click For Summary

Discussion Overview

The discussion revolves around minimizing a circuit for a given expression, focusing on the correctness of two circuit diagrams that yield the same result. Participants seek clarification on the validity of their diagrams and the handling of inverted terms.

Discussion Character

  • Homework-related, Debate/contested, Technical explanation

Main Points Raised

  • One participant presents two circuit diagrams derived from a minimized expression and questions their correctness.
  • Another participant expresses confusion regarding a specific aspect of the first circuit and questions whether it contains an error.
  • Some participants assert that there is no error in the first circuit, while others seek clarification on the handling of inverted terms.
  • A participant notes that the second circuit explicitly shows how the inverted term b- is generated, contrasting it with the first circuit.
  • There is a discussion about whether participants are expected to assume the availability of inverted terms or if they need to create them independently.
  • Clarification is sought regarding which circuit diagram is being referenced when discussing the generation of b-.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the correctness of the circuit diagrams, and there are competing views regarding the treatment of inverted terms.

Contextual Notes

Some assumptions about the availability of inverted terms and the clarity of circuit diagrams remain unresolved.

Summary: circuit diagram from minimize expression

I am drawing a circuit diagram from a minimize expression. I have come up with two circuit diagrams that give same result.
I am not sure which of the circuit diagram (1) or (2) is correct. Are both my diagram correct? Need help

I don't understand this in the first circuit. Is it an error?

No. This is not error

So inverting b- gives you back b- ?
 
That is not b- . I crossed out that.

Let me post clean image again.. please see this

Well, they are the same then. The only difference is that you explicitly show how you generate b- in the 2nd case. Are you supposed to assume that you have all terms and inversions, or do you need to make your own inverted terms?

did you mean 1st case?

Oops, you are correct. I meant your first case. In the 2nd case, you seem to have b- available to use as an input without having to make it yourself.
