next qvestion, can you help me make this function Y=A′B′C′D+A′BC′D+A′B′CD′+A′BCD+AB′C′D′+AB′CD+ABC′D+ABCD′,  be easy to implement using transmission gates

To implement the Boolean function \( Y = A'B'C'D + A'BC'D + A'B'CD' + A'BCD + AB'C'D' + AB'CD + ABC'D + ABCD' \) using transmission gates, it's helpful to simplify the function first using Boolean algebra, if possible, and then convert it into a suitable form for implementation with transmission gates.

### Step 1: Simplify the Boolean Function

Let's start by grouping terms and see if we can simplify the expression:

\[
Y = A'B'C'D + A'BC'D + A'B'CD' + A'BCD + AB'C'D' + AB'CD + ABC'D + ABCD'
\]

Grouping terms:

\[
Y = A'(B'C'D + BC'D + B'CD' + BCD) + A(B'C'D' + BCD + BC'D + B'C'D')
\]

Let's simplify each group separately.

1. For \( A' \):
   \[
   B'C'D + BC'D + B'CD' + BCD = C'D(B' + B) + CD'(B' + B) = C'D + CD' = C \oplus D
   \]
   So, \( A'(C \oplus D) \).

2. For \( A \):
   \[
   B'C'D' + BCD + BC'D + B'C'D' = C'D'(B' + B) + CD(B' + B) = C'D' + CD = C \oplus D
   \]
   So, \( A(C \oplus D) \).

Thus, the simplified function is:

\[
Y = A'(C \oplus D) + A(C \oplus D)
\]

This simplifies further as:

\[
Y = C \oplus D
\]

### Step 2: Implement the Simplified Function Using Transmission Gates

Now that the Boolean function \( Y = C \oplus D \) (which is an XOR function) is simplified, you can implement it using transmission gates.

#### Transmission Gate XOR Implementation:
1. **Inputs:** \( C \) and \( D \).
2. **Outputs:** \( Y = C \oplus D \).

The XOR function can be implemented as follows:

- **Output Y = C \oplus D:**
   - Use two transmission gates:
     - For \( Y = C \) when \( D = 0 \).
     - For \( Y = D \) when \( C = 0 \).

**Implementation steps:**
1. **Gate 1:** Connect input \( C \) to output \( Y \) and control with \( D' \).
2. **Gate 2:** Connect input \( D \) to output \( Y \) and control with \( C' \).
3. Combine the outputs of the two transmission gates.

### Circuit Description:
- **Transmission Gate 1:** Controlled by \( D' \), passes \( C \).
- **Transmission Gate 2:** Controlled by \( C' \), passes \( D \).

This will produce the output \( Y = C \oplus D \), which is the simplified version of your original function.

### Verification:
To ensure that the simplified implementation correctly represents the original function, verify each case:
- When \( C = 0 \) and \( D = 0 \), \( Y = 0 \).
- When \( C = 0 \) and \( D = 1 \), \( Y = 1 \).
- When \( C = 1 \) and \( D = 0 \), \( Y = 1 \).
- When \( C = 1 \) and \( D = 1 \), \( Y = 0 \).

### Conclusion:
The original Boolean function can be implemented with just an XOR gate using transmission gates, significantly simplifying the circuit.
