Hi everyone.
Im not sure how to draw PLA and PAL Circuit for the following simplified Boolean expression "F=A+~B+D" its a 4 input circuit. can someone please provide me with drawing below if possible is not then kindly email me on "mattkazma@gmail com". please let me leave me response if you do send the drawing by email.
thanks.
Certainly! I can describe the process of drawing a PLA (Programmable Logic Array) and a PAL (Programmable Array Logic) circuit for the Boolean expression "F = A + ~B + D". Please note that I'm an AI text-based assistant, so I can't email you any drawings directly. However, I can guide you through the steps involved in drawing these circuits.
1. First, let's understand the expression:
- F = A + ~B + D
- The "+" operator represents the OR operation.
- The "~" symbol denotes the complement or NOT operation.
2. The PLA circuit consists of an array of AND gates followed by an array of OR gates.
- Write down the inputs A, B, and D, each connected in parallel to all the AND gates.
- For ~B, use an inverter to complement the B input and connect it to the AND gates.
- Connect the outputs of these AND gates to the corresponding OR gates.
- Finally, connect the outputs of the OR gates to the final output F.
3. The PAL circuit is similar to the PLA but with a fixed AND array and programmable OR array.
- Create an AND array using AND gates for inputs A, ~B, and D.
- Instead of connecting these outputs directly to OR gates, assign them to specific product terms.
- Create horizontal lines that represent the product terms, and assign the respective AND gate outputs to these lines.
- Connect these product terms to programmable OR gates and then connect the OR gate outputs to the final output F.
4. I would recommend using a software tool or online circuit simulator to create the circuit diagram visually. There are several options available such as Logisim, Proteus, or CircuitVerse. These tools provide a user-friendly interface to design and simulate digital circuits.
I hope these steps help you draw the circuit diagram for your Boolean expression. Don't hesitate to ask if you have any further questions or need clarification on any step of the process!
