Question

What is the function of the following circuit? Give your answer in minimized sum-of-products (SOP) form. (see attached).

 

Please explain how the truth tables were built

This diagram illustrates a digital logic circuit involving a multiplexer, an AND gate, and a NOT gate. Here's a detailed explanation:

1. **Multiplexer (MUX)**:
   - The MUX has four data inputs labeled from `00` to `11`.
   - It has two selector inputs marked `S1:0`.
   - The output of the MUX is labeled `Y`.
   - A switch labeled `AC` affects the input `S2`, hinting at an additional control or selection function.

2. **Inputs**:
   - Input `B` is connected directly to the data input `00` of the MUX.
   - Input `C` passes through a NOT gate (inverter), which means that the input is logically negated before connecting to data input `10` of the MUX.
   - Inputs `A` and `B` are connected to an AND gate. The output of this AND gate connects to data input `11` of the MUX.

3. **Logic Gates**:
   - The **AND Gate**: It takes two inputs, `A` and `B`. Its output is high only when both `A` and `B` are high.
   - The **NOT Gate**: It takes input `C`. Its output is the inverse of `C`, meaning it outputs high when `C` is low and vice versa.

In summary, this setup uses a multiplexer to route one of several input signals to the output `Y`, based on the values of the selection inputs and the states of the logic gates.
