### Prime Implicants and K-Maps
#### 7. Task:
Determine the number of prime implicants (PI), distinguished 1-cells, and essential prime implicants (EPI) for the given Karnaugh maps (K-maps).
#### Implicant Terminology:
- **Implicant**:
- A bubble covering only 1s (each bubble must be a power of 2 in size).
- **Prime Implicant**:
- A bubble expanded to the largest possible size (while maintaining powers of 2).
- **Essential Prime Implicant**:
- A bubble containing a 1 covered exclusively by it and not by any other prime implicant bubble.
- **Non-essential Prime Implicant**:
- A 1 that can be covered by multiple prime implicant bubbles.
#### Explanation of the Diagram (K-map E):
- The K-map is labeled with variables A, B on the top and C, D on the side. Each cell represents a binary combination of these variables.
- Cells containing the value "1" have been circled in red. These circles represent the implicants.
- The K-map layout is as follows:
```
AB
\ 00 01 11 10
CD
00 0 1 1 0
01 1 0 1 0
11 1 1 0 1
10 1 0 0 1
```
- Red circles highlight the following cells:
- (C=0,D=1; A=0,B=1)
- (C=0,D=0; A=0,B=1)
- (C=1,D=1; A=0,B=0)
- (C=1,D=1; A=1,B=0)
- (C=1,D=0; A=0,B=0)
- Others as covered in the layout.
Each circle represents an implicant that can potentially be a prime implicant or essential depending on overlap and coverage by other red circles.
