What is the group of 1s present in 8 cells of a K – map called?a.Pairb.Octavec.Quadd.Octet

To determine the answer to the question regarding the group of 1s in a Karnaugh map (K-map), let's break down the problem and analyze the options given.

Break Down the Problem

1. We need to identify terminology related to groups of 1s on a K-map.
2. Specifically, we are looking for the term that describes a group of 1s consisting of 8 cells.

Relevant Concepts

• In K-map terminology:
  • A single 1 is referred to as a "minterm."
  • A group of 2 cells is called a "pair."
  • A group of 4 cells is known as a "quadro" (or quad).
  • A group of 8 cells is called an "octet."
  • A group of 16 cells would be a "octadec."

Analysis and Detail

Now, let's analyze the answer choices:

1. a. Pair - refers to 2 cells with 1s.
2. b. Octave - not a standard term in K-map context.
3. c. Quad - refers to 4 cells with 1s.
4. d. Octet - this term correctly describes a group of 8 cells.

Verify and Summarize

After matching the concepts with the answer choices, it's clear that "Octet" is the correct term for a group of 1s in 8 cells.

Final Answer

The answer is d. Octet.
