Question
**Convert the following circuit to a Boolean equation (do not simplify):**

The diagram illustrates a digital logic circuit composed of several logic gates. The circuit consists of three inputs labeled `a`, `b`, and `c`, and one output labeled `F`.

1. **AND, OR, and NOT Gates:**

   - The input `a` is connected to a NOT gate, generating the output `¬a` (NOT a).
   - Inputs `a` and `b` are fed into a three-input AND gate. The third input is `¬c`, which comes from a NOT gate connected to `c`.
   - The output of this AND gate is one of the inputs to the final OR gate.

2. **Intermediate Processing:**
   
   - Inputs `a`, `b`, and `c` are combined in a second AND gate.
   - This AND gate’s output is fed into the same OR gate previously mentioned.

3. **Final Processing:**
   
   - Both outputs from the two AND gates are fed into an OR gate. The output of this OR gate is the final output `F`.

**Boolean Equation:**

The Boolean equation for the circuit can be written as:

\[ F = (¬a \cdot b \cdot ¬c) + (a \cdot b \cdot c) \]

This equation represents the output `F` as a sum (OR) of the products (ANDs) of the inverted and non-inverted inputs.

Expert Solution
Step 1

The AND gate is an electronic circuit that gives a high output (1) only if all its inputs are high.  A dot (.) is used to show the AND operation i.e. A.B.  

The OR gate is an electronic circuit that gives a high output (1) if one or more of its inputs are high.  A plus (+) is used to show the OR operation.

The NOT gate is an electronic circuit that produces an inverted version of the input at its output. This is shown as A', or A with a bar over the top.
