can you minimize that y function, so that it is easy to draw it using transmission gates

To minimize the Boolean function \( Y = A′B′C′D + A′BC′D + A′B′CD′ + A′BCD + AB′C′D′ + AB′CD + ABC′D + ABCD′ \) for implementation using transmission gates, we'll further simplify it using Karnaugh maps (K-maps). This method helps in identifying common groups of variables, leading to a minimized expression.

### Step 1: Set Up the Karnaugh Map
We'll use a 4-variable K-map (for variables \( A, B, C, \) and \( D \)).

#### Grouping Terms in K-map
The terms can be placed in the K-map as follows:

\[
\begin{array}{c|c|c|c|c}
AB \backslash CD & 00 & 01 & 11 & 10 \\
\hline
00 & 0 & 1 & 0 & 1 \\
01 & 1 & 0 & 1 & 0 \\
11 & 0 & 1 & 0 & 1 \\
10 & 1 & 0 & 1 & 0 \\
\end{array}
\]

### Step 2: Identify Groups
From the K-map, we can group the ones (1s) to minimize the function. Here are the groups:

1. **Group 1 (2 cells):** Covers \( A′B′C′D \) and \( A′BC′D \) 
   - Expression: \( A′C′D \)
   
2. **Group 2 (2 cells):** Covers \( A′B′CD′ \) and \( A′BCD \)
   - Expression: \( A′D′C \)

3. **Group 3 (2 cells):** Covers \( AB′C′D′ \) and \( AB′CD \)
   - Expression: \( AB′D′ \)

4. **Group 4 (2 cells):** Covers \( ABC′D \) and \( ABCD′ \)
   - Expression: \( ABC′D \)

### Step 3: Simplify the Expression
The groups lead to the following simplified Boolean expression:

\[
Y = A′C′D + A′D′C + AB′D′ + ABC′D
\]

### Step 4: Minimize Further
Notice that the minimized expression is already in a reduced form where each term cannot be combined further. Therefore, this is the final minimized expression suitable for implementation with transmission gates:

\[
Y = A′C′D + A′D′C + AB′D′ + ABC′D
\]

### Transmission Gate Implementation:
Each term corresponds to a combination of transmission gates. The expression can be implemented using the following logic:

1. **\( A′C′D \)**: Implemented using a transmission gate controlled by \( A′ \), \( C′ \), and \( D \).
2. **\( A′D′C \)**: Implemented using a transmission gate controlled by \( A′ \), \( D′ \), and \( C \).
3. **\( AB′D′ \)**: Implemented using a transmission gate controlled by \( A \), \( B′ \), and \( D′ \).
4. **\( ABC′D \)**: Implemented using a transmission gate controlled by \( A \), \( B \), \( C′ \), and \( D \).

This minimized form makes it straightforward to implement with minimal logic and transmission gates.
