Implementation Procedure
- Prepare the truth table
- Write the Boolean expression in SOP (sum of products) form.
- Obtain the minimum SOP form to reduce the number of product terms to a minimum.
- Decide the input connection of the AND matrix for generating the required product term.
- Then decide the input connections of OR matrix to generate the sum terms.
- Decide the connections of invert matrix.
- Program the PLA.
